while loop

The while statement is also a looping statement. The while loop evaluates the test expression before every loop, so it can execute zero times if the condition is initially false. It has the following syntax.

while (expression)
Statement 1;
Statement 2;
Statement n;

Here the initialization of a loop control variable is generally done before the loop separately. The testing of the condition is done in while by evaluating the expression within the parenthesis. If the evaluation result is true value, the block of statement within calibrates is executed. If the evaluation result is false value the block of statements within the body of loop is skipped and the loop execution get terminated with the control passing to the statement immediately following the while construct. The increment or decrement of the loop control variable is generally done within the body of the loop.

The following example illustrates the use of while loop.
