what is do while loop in c language

Question

Shivam Payasi · Answer

A do-while loop is a loop construct in the C programming language that allows a certain block of code to be executed repeatedly until a specified condition is met. The key difference between a do-while loop and other loop constructs (such as the while loop) is that the condition is checked at the end of the loop iteration, meaning that the block of code will always execute at least once. The syntax for a do-while loop in C is as follows: do { // block of code to be executed } while (condition); The block of code within the do-while loop will execute first, and then the condition will be checked. If the condition evaluates to true, the loop will continue executing, and if it evaluates to false, the loop will terminate, and the program will move on to the next line of code after the loop. The main advantage of a do-while loop is that it guarantees that the block of code will execute at least once, regardless of whether the condition is initially true or false. This can be useful in situations where you want to validate user input or perform some initialization before entering the loop.
