Do-While Loop Syntax
The syntax of a do-while loop is as follows:
do {
// Statements to be executed
} while (condition);
- The block of statements within the
do
block is executed unconditionally for the first time. - After executing the block, the condition specified after the
while
keyword is evaluated. - If the condition evaluates to
true
, the loop body is executed again. If the condition evaluates tofalse
, the loop terminates, and program execution moves to the next statement after the loop.
Here’s a breakdown of each component of the syntax:
do
: This keyword initiates the do-while loop and precedes the block of statements to be executed.{}
: These braces enclose the block of statements to be executed within the loop.while
: This keyword specifies the condition to be evaluated after the execution of the loop body.condition
: This is the expression that determines whether the loop should continue iterating. If the condition evaluates totrue
, the loop continues; if it evaluates tofalse
, the loop terminates.
Do-While loop in Programming
Do-while loop is a control flow statement found in many programming languages. It is similar to the while loop, but with one key difference: the condition is evaluated after the execution of the loop’s body, ensuring that the loop’s body is executed at least once. In this article, we will learn about the basics of Do while loop, its syntax and its usage in different languages.
