The While Loop

Lesson Details:

I: Introduction

This article will discuss the different programming languages and the benefits and problems we face using certain programming languages.

A: Introduction to programming coding languages

Programming is the process of designing and writing computer programs, which are used to specify the behavior of a machine or procedure so that it solves a problem or satisfies a need. Programming can be done in various languages, but all these languages have one thing in common that they are read by humans [1]. [2] [3] [4].

II: Body

In this section, I will discuss the while loop in detail. It is a very popular feature among programmers. The while loop allows us to perform a certain operation repeatedly until a specific condition is satisfied. It has a block of instructions which are repeated until the condition is satisfied at which point execution resumes after the closing curly brace. Consider the following example:

Example-1: The while loop

int x = 0; while(x < 1000){ Console.WriteLine("x is :" + x); x++; } 1 2 3 4 5 6 7 int x = 0 ; while ( x < 1000 ) { Console . WriteLine ( "x is :" + x ) ; x ++ ; }

In this example, we have a variable named ‘x’ which starts with zero value. We have a condition in place which checks whether x is less than 1000 or not. As long as it is less than 1000, the loop will continue looping till it reaches 1000. In order to know when x reaches 1000, we have written another statement at the end of the loop block i.e. x++ which means, increment the value of x by 1 each time after executing the entire loop block.

III: Conclusion

To conclude, I would say programming languages are very crucial for any computer system to function properly. There are few programming languages which are used widely across the globe including C#, Java, PHP, Python etc. There are also some programming languages that are developed by companies like Apple, Google etc. One of the most popular programming language used nowadays is Python. It is an object oriented programming language which was developed by Guido van Rossum in 1991. It is mainly based on English language and has simple syntax based on whitespace indentations. While designing programs in python, we need to create classes and methods for proper functioning of programs. Python can be used to develop web applications as well as desktop applications. There are several libraries available in Python which make it easy to develop apps quickly. This language has many advantages like its simple syntax, easy to learn, cross platform compatibility etc.
