Do vs while C++?

| While Loop | Do-While Loop |
|---|---|
| This is entry controlled loop. It checks condition before entering into loop | This is exit control loop. Checks condition when coming out from loop |
| The while loop may run zero or more times | Do-While may run more than one times but at least once. |

Do while in C programming?
The do-while loop is mainly used in the case where we need to execute the loop at least once. The do-while loop is mostly used in menu-driven programs where the termination condition depends upon the end user. The syntax of the C language do-while loop is given below: printf (“n1. Print Hellon2. Print Javatpointn3. Exitn”);
Do WHILE loop JavaScript syntax?

Do WHILE loop in C programming?
Unlike for and while loops, which test the loop condition at the top of the loop, the do…while loop in C programming checks its condition at the bottom of the loop.

Do WHILE LOOP Java syntax?
The syntax of the while loop is: while (testExpression) { // body of loop } Here, A while loop evaluates the textExpression inside the parenthesis ().
