An assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. [1]

The assignment operator allows us to change the value of a modifiable data object (for beginning programmers this typically means a variable). It is associated with the concept of moving a value into the storage location (again usually a variable). Within most programming languages the symbol used for assignment is the equal symbol. But bite your tongue, when you see the = symbol you need to start thinking: assignment. The assignment operator has two operands. The one to the left of the operator is usually an identifier name for a variable. The one to the right of the operator is a value.

Simple Assignment

The value 21 is moved to the memory location for the variable named: age. Another way to say it: age is assigned the value 21.

Assignment with an Expression

The item to the right of the assignment operator is an expression. The expression will be evaluated and the answer is 14. The value 14 would be assigned to the variable named: total_cousins.

Assignment with Identifier Names in the Expression

The expression to the right of the assignment operator contains some identifier names. The program would fetch the values stored in those variables; add them together and get a value of 44; then assign the 44 to the total_students variable.

Assignment Statement

An Assignment statement is a statement that is used to set a value to the variable name in a program .

Assignment statement allows a variable to hold different types of values during its program lifespan. Another way of understanding an assignment statement is, it stores a value in the memory location which is denoted by a variable name.

The symbol used in an assignment statement is called as an operator . The symbol is ‘=’ .

Note: The Assignment Operator should never be used for Equality purpose which is double equal sign ‘==’.

The Basic Syntax of Assignment Statement in a programming language is :

variable = expression ;

variable = variable name

expression = it could be either a direct value or a math expression/formula or a function call

Few programming languages such as Java, C, C++ require data type to be specified for the variable, so that it is easy to allocate memory space and store those values during program execution.

data_type variable_name = value ;

In the above-given examples, Variable ‘a’ is assigned a value in the same statement as per its defined data type. A data type is only declared for Variable ‘b’. In the 3 rd line of code, Variable ‘a’ is reassigned the value 25. The 4 th line of code assigns the value for Variable ‘b’.

Assignment Statement Forms

This is one of the most common forms of Assignment Statements. Here the Variable name is defined, initialized, and assigned a value in the same statement. This form is generally used when we want to use the Variable quite a few times and we do not want to change its value very frequently.

Tuple Assignment

Generally, we use this form when we want to define and assign values for more than 1 variable at the same time. This saves time and is an easy method. Note that here every individual variable has a different value assigned to it.

(Code In Python)

Sequence Assignment

(Code in Python)

Multiple-target Assignment or Chain Assignment

In this format, a single value is assigned to two or more variables.

Augmented Assignment

In this format, we use the combination of mathematical expressions and values for the Variable. Other augmented Assignment forms are: &=, -=, **=, etc.

Few Rules for Assignment Statement

Few Rules to be followed while writing the Assignment Statements are:

Variable names must begin with a letter, underscore, non-number character. Each language has its own conventions.
The Data type defined and the variable value must match.
A variable name once defined can only be used once in the program. You cannot define it again to store other types of value.
If you assign a new value to an existing variable, it will overwrite the previous value and assign the new value.

Assignment Operators in C

In C language, the assignment operator stores a certain value in an already declared variable. A variable in C can be assigned the value in the form of a literal, another variable, or an expression.

The value to be assigned forms the right-hand operand, whereas the variable to be assigned should be the operand to the left of the " = " symbol, which is defined as a simple assignment operator in C.

In addition, C has several augmented assignment operators.

The following table lists the assignment operators supported by the C language −

Simple Assignment Operator (=)

The = operator is one of the most frequently used operators in C. As per the ANSI C standard, all the variables must be declared in the beginning. Variable declaration after the first processing statement is not allowed.

You can declare a variable to be assigned a value later in the code, or you can initialize it at the time of declaration.

You can use a literal, another variable, or an expression in the assignment statement.

Once a variable of a certain type is declared, it cannot be assigned a value of any other type. In such a case the C compiler reports a type mismatch error.

In C, the expressions that refer to a memory location are called "lvalue" expressions. A lvalue may appear as either the left-hand or right-hand side of an assignment.

On the other hand, the term rvalue refers to a data value that is stored at some address in memory. A rvalue is an expression that cannot have a value assigned to it which means an rvalue may appear on the right-hand side but not on the left-hand side of an assignment.

Variables are lvalues and so they may appear on the left-hand side of an assignment. Numeric literals are rvalues and so they may not be assigned and cannot appear on the left-hand side. Take a look at the following valid and invalid statements −

Augmented Assignment Operators

In addition to the = operator, C allows you to combine arithmetic and bitwise operators with the = symbol to form augmented or compound assignment operator. The augmented operators offer a convenient shortcut for combining arithmetic or bitwise operation with assignment.

For example, the expression "a += b" has the same effect of performing "a + b" first and then assigning the result back to the variable "a".

Run the code and check its output −

Similarly, the expression "a <<= b" has the same effect of performing "a << b" first and then assigning the result back to the variable "a".

Here is a C program that demonstrates the use of assignment operators in C −

When you compile and execute the above program, it will produce the following result −

Functional Programming 101

A deep dive on the benefits of functional programming and why it’s actually easier than you think.

Artwork: Kasia Bojanowska

Cassidy Williams // CTO, Contenda

The ReadME Project amplifies the voices of the open source community: the maintainers, developers, and teams whose contributions move the world forward every day.

Functional programming is a hot topic. The 2021 Developer Survey from Stack Overflow ranked functional languages among the most loved. Popular JavaScript libraries like React and Angular let you use functional concepts in your components, traditionally object-oriented languages have added functional support... and yet there’s been some confusion about what functional programming actually means.

Traditionally, folks often think that it’s a concept that you should learn when you are deeper into your development career, but that’s not necessarily the case!

“I think functional programming is more accessible for someone trying to teach themselves to program. I’ve seen folks from all sorts of backgrounds come onto the Elixir Wizards podcast and tell me that Elixir clicked for them when they were starting out because of the pipe operator. The pipe ( `|>` ) makes it easier for beginners to recognize what their code is doing, with a clear pipeline of what they started with, how it changed, and the final outcome. Generally, I think functional programming reads more like spoken language.” - Sundi Myint, co-host of the Elixir Wizards podcast

If you’re ready for it, let’s take a deep dive into what functional programming is, how it differs from other paradigms, why you would use it, and how to get started!

What is functional programming?

There are three “types” of programming that you may or may not know: procedural programming, object-oriented programming, and functional programming. I’ll focus on the latter two.

In object-oriented programming (OOP), you create “objects” (hence the name), which are structures that have data and methods. In functional programming, everything is a function. Functional programming tries to keep data and behavior separate, and OOP brings those concepts together.

“Functional programming [is] a paradigm that forces us to make the complex parts of our system explicit, and that’s an important guideline when writing software.” - José Valim, creator of Elixir

What are the rules of functional programming?

There are two main things you need to know to understand the concept:

Data is immutable: If you want to change data, such as an array, you return a new array with the changes, not the original.

Functions are stateless: Functions act as if for the first time, every single time! In other words, the function always gives the same return value for the same arguments.

There are three best practices that you should generally follow:

Your functions should accept at least one argument.

Your functions should return data, or another function.

Don’t use loops!

Now, some of these things can happen in object-oriented programming as well. Some languages allow you to mix-and-match concepts, too, like JavaScript for example.

An example to show the difference between OOP and functional programming

Let’s say that you have a school and we have the records of each of the students in some database. Let’s say they all have a name and a grade point average (GPA). In object-oriented programming, you might write something like this:

If you wanted to initialize a student, you might do something like this:

Now let’s say you want to change the GPAs of a bunch of students. With OOP, you could have an array of the students:

And to change each of their GPAs, you could do a loop to increase the grades of each.

…or something. Then you could loop through again to print out the results, or just work with the objects as you wish.

Now, if you wanted to solve the same type of problem with functional programming, you’d do it a little differently. This is how you might initialize the students:

We’re storing the students as plain arrays instead of objects. Functional programming prefers plain data structures like arrays and lists and hashes (etc.) to not “complicate” the data and behavior. So next, instead of writing just one changeGPA() function that you loop over, you’d have a changeGPAs() function and a changeGPA() function.

The function changeGPAs() would take in the students’ array. It would then call changeGPA() for each value in the students array, and return the result as a new array. The job of changeGPA() is to return a copy of the student passed in with the GPA updated. The point of this is because functional programming prefers tiny, modular functions that do one part of a larger job! The job of changeGPAs() is to handle the set of students, and the job of changeGPA() is to handle each individual student. Also note that the original array doesn’t change because we treat data as immutable in functional programming. We create new datasets instead of modifying existing ones.

Why would I use functional programming?

When you think about well-structured software, you might think about software that’s easy to write, easy to debug, and where a lot of it is reusable. That’s functional programming in a nutshell! Granted, one might argue that it’s not as easy to write, but let’s touch on the other two points while you wrap your mind around the functional paradigm.

“Once you get used to it, it’s self-evident. It’s clear. I look at my function. What can it work with? Its arguments. Anything else? No. Are there any global variables? No. Other module data? No. It’s just that.” - Robert Virding, co-inventor of Erlang

Debugging functional programming is arguably significantly easier than other programming paradigms because of its modularity and lack of side effects.

If something went wrong in your software using OOP, you would have to think about what other parts of your program might have done previously that could affect your program’s state. With functional programming, you can pinpoint the exact function where something went wrong, because certain things can only happen at one point.

For example, let’s say we had a counter that skipped the number 5.

In this program, if you want to test it, you’d have to keep track of the global state of count, and run the `increment()` function 5 times to make sure it worked, every single time. `increment()` returns something different every time it is called, so you need to use a debugger to step through your program.

Meanwhile, if you wrote this function in a functional way:

We don’t need to run `pureIncrement()` multiple times to check this. You can easily unit test the function because it will always return the same thing with the same input, and there is no variable being modified (remember, immutability)!

Now, that isn’t to say that you’ll never use a debugger (I won’t get into that in this article), but by having everything written into smaller chunks and free from side effects, your errors will be much faster to pinpoint, and won’t be dependent on the environment they’re being run in.

Reusability

As you saw in our student example, we broke down the functions into smaller functions. In every functional program you write, you break functions down to be as small as they can be. It’s kind of like breaking up a complex math problem into parenthesis.

Let’s say that you want to solve a math problem, like:

(6 * 9) / ((4 + 2) + (4 * 3)) If you were doing this by hand, you could break up the problem by adding/multiplying all of the numbers, combining what is in the parenthesis, and then dividing the results.

If you were doing this in a functional language, like Lisp, for example, it looks incredibly similar:

This is why functional programming is often referred to as “pure programming!" Functions run as if they are evaluating mathematical functions, with no unintended side effects.

“ Purity ” by xkcd is licensed under CC BY-NC 2.5

When you have such small, pure functions, you can often reuse them much more easily than your traditional object-oriented program. This is a controversial take (if you look up “functional programming reuse” you will find many discussions and podcasts on the subject), so hang in with me here: When you want to reuse a class in OOP and add a feature, typically you add conditionals and parameters, and your functions get larger. Your abstract classes and interfaces get pretty robust. You have to pay careful attention to the larger application architecture because of side effects and other factors that will affect your program (like we talked about before). In functional programming, it’s the opposite in that your functions get smaller and much more specific to what you want. One function does one thing, and whenever you want to do that one thing, you use that one function.

There are exceptions in every system, of course, but this is generally what you see in various codebases out in the world!

Okay, okay, I’m sold. How do I get started?

If you’re already comfortable with JavaScript or Python, you can get started right away trying out functional programming concepts like we’ve talked about here. If you’d like to get more into the nitty-gritty of “pure” languages that are designed for functional programming, you can try out the Lisp family (including Common Lisp, Scheme, and Clojure), the ML family (including OCaml and F#), Erlang, Elixir, Elm, or Haskell.

Functional programming can be a little mind-bending as you get used to it. But if you give it a chance and try it out, your development and production environments will be robust, your software will be easier to debug, and you’ll enjoy the guarantees you get from the solid foundations of functional programming!

Solving Assignment Problem using Linear Programming in Python

Learn how to use Python PuLP to solve Assignment problems using Linear Programming.

In earlier articles, we have seen various applications of Linear programming such as transportation, transshipment problem, Cargo Loading problem, and shift-scheduling problem. Now In this tutorial, we will focus on another model that comes under the class of linear programming model known as the Assignment problem. Its objective function is similar to transportation problems. Here we minimize the objective function time or cost of manufacturing the products by allocating one job to one machine.

If we want to solve the maximization problem assignment problem then we subtract all the elements of the matrix from the highest element in the matrix or multiply the entire matrix by –1 and continue with the procedure. For solving the assignment problem, we use the Assignment technique or Hungarian method, or Flood’s technique.

The transportation problem is a special case of the linear programming model and the assignment problem is a special case of transportation problem, therefore it is also a special case of the linear programming problem.

In this tutorial, we are going to cover the following topics:

Assignment Problem

A problem that requires pairing two sets of items given a set of paired costs or profit in such a way that the total cost of the pairings is minimized or maximized. The assignment problem is a special case of linear programming.

For example, an operation manager needs to assign four jobs to four machines. The project manager needs to assign four projects to four staff members. Similarly, the marketing manager needs to assign the 4 salespersons to 4 territories. The manager’s goal is to minimize the total time or cost.

Problem Formulation

A manager has prepared a table that shows the cost of performing each of four jobs by each of four employees. The manager has stated his goal is to develop a set of job assignments that will minimize the total cost of getting all 4 jobs.

Initialize LP Model

In this step, we will import all the classes and functions of pulp module and create a Minimization LP problem using LpProblem class.

Define Decision Variable

In this step, we will define the decision variables. In our problem, we have two variable lists: workers and jobs. Let’s create them using LpVariable.dicts() class. LpVariable.dicts() used with Python’s list comprehension. LpVariable.dicts() will take the following four values:

First, prefix name of what this variable represents.
Second is the list of all the variables.
Third is the lower bound on this variable.
Fourth variable is the upper bound.
Fourth is essentially the type of data (discrete or continuous). The options for the fourth parameter are LpContinuous or LpInteger .

Let’s first create a list route for the route between warehouse and project site and create the decision variables using LpVariable.dicts() the method.

Define Objective Function

In this step, we will define the minimum objective function by adding it to the LpProblem object. lpSum(vector)is used here to define multiple linear expressions. It also used list comprehension to add multiple variables.

Define the Constraints

Here, we are adding two types of constraints: Each job can be assigned to only one employee constraint and Each employee can be assigned to only one job. We have added the 2 constraints defined in the problem by adding them to the LpProblem object.

Solve Model

In this step, we will solve the LP problem by calling solve() method. We can print the final value by using the following for loop.

From the above results, we can infer that Worker-1 will be assigned to Job-1, Worker-2 will be assigned to job-3, Worker-3 will be assigned to Job-2, and Worker-4 will assign with job-4.

In this article, we have learned about Assignment problems, Problem Formulation, and implementation using the python PuLp library. We have solved the Assignment problem using a Linear programming problem in Python. Of course, this is just a simple case study, we can add more constraints to it and make it more complicated. You can also run other case studies on Cargo Loading problems , Staff scheduling problems . In upcoming articles, we will write more on different optimization problems such as transshipment problem, balanced diet problem. You can revise the basics of mathematical concepts in this article and learn about Linear Programming in this article .

Assignment Operators in Programming
Assignment operators are used in programming to assign values to variables. We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign (=), which assigns the value on the right side of the operator to ...
Assignment (computer science)
Assignment (computer science) In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location (s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.
