While Loop Syntax
The syntax of a while loop is straightforward:
while (condition){
# Code to be executed while the condition is true
}
The loop continues to execute the block of code within the loop as long as the condition evaluates to true. Once the condition becomes false, the loop terminates, and program execution proceeds to the subsequent statement.
In this syntax:
condition
is the expression or condition that is evaluated before each iteration. If the condition is true, the code block inside the loop is executed. If the condition is false initially, the code block is skipped, and the loop terminates immediately.- The code block inside the loop is indented and contains the statements to be executed repeatedly while the condition remains true.
While loops are particularly useful when the number of iterations is uncertain or dependent on dynamic conditions. They allow for flexible iteration based on changing circumstances within a program.
While loop in Programming
While loop is a fundamental control flow structure in programming, enabling the execution of a block of code repeatedly as long as a specified condition remains true. While loop works by repeatedly executing a block of code as long as a specified condition remains true. It evaluates the condition before each iteration, executes the code block if the condition is true, and terminates when the condition becomes false. This mechanism allows for flexible iteration based on changing conditions within a program.
In this post, we will explore the while loop, its syntax, functionality, and applications across various programming domains.
