Learn about While and Do While loops in Kotlin

While and Do While are two types of loops that are supported in Kotlin and we will learn about them in this article.

Learn about While loop in Python

While loop statement in Python programming language repeatedly executes a target statement as long as a given condition is true.

C++

while loop in C++

while loop is a most basic loop in C++. while loop has one control condition, and executes as long the condition is true. The condition of the loop is tested before the body of the loop is executed, hence it is called an entry-controlled loop.

C Programming

While loop in C

Order execution of while loop in C is control variable is initialized, test expression is evaluated, if it evaluates to true, the loop enters the body and it is repeatedly executed, till the expression does not evaluate to false. When the test expression evaluates to false, the loop is exited.

Software Engineering

while loop in Java

A while loop is an entry controlled control flow statement that allows code to be executed repeatedly based on a given condition. In Java, while loop is widely used. On benchmarking the performance, we see that while loop is slower than for loop but is two times faster than do while loop.

control statement

do while loop control statement

A do-while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time. The do-while loop checks its condition at the bottom of the loop after one time execution of do.

A while loop is a control flow statement that allows code to be executed repeatedly based on a given condition. We have provided a flow chart, syntax and programming example to demonstrate while loop
