2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true or false but this is not the case with while. While loop is executed only when the condition is true. Syntax: do{ //code }whil...
The do-while statement lets you repeat a statement or compound statement until a specified expression becomes false. Syntax iteration-statement: do statement while ( expression ) ; The expression in a do-while statement is evaluated after the body of the loop is executed. Therefore, the body ...

Output of while loop: Output of do-while loop: b: 11 Note that thewhileloop doesn't take any iterations, but thedo-whileexecutes its body once. This is because the looping condition is verified at the top of the loop block in case ofwhile, and since the condition is false, the progr...

3. While Loop Examples It is another loop like ‘do-while’ loop in C. The ‘while’ loop allows execution of statements inside block of loop only if condition in loop succeeds. Basic syntax to use ‘while’ loop is: variable initialization; ...
