Computer languages assist us in getting the results that are difficult to obtain manually. These high-level languages operate on a defined structure of commands. A loop is a command that tends to repeat itself to obtain the desired result.

These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop. On the other hand, the do-while loop verifies the condition after the execution of the statements inside the loop.

do while loop in C

Previously you have learned about while loop and do while loop in C. Now, we will see the basic difference between while and do while with example. Prerequisites:- while loop in C programming do-while loop in C programming. The while loop is pre-test loop , where firstly the condition is checked and if the condition is true then only the statements of the while loop execute. The do-while loop is a post-test loop.

A Loop executes the sequence of statements many times until the stated condition becomes false. A loop consists of two parts, a body of a loop and a control statement. The control statement is a combination of some conditions that direct the body of the loop to execute until the specified condition becomes false. The purpose of the loop is to repeat the same code a number of times. Types of Loops in C Depending upon the position of a control statement in a program, looping in C is classified into two types: 1.

Documentation Help Center. An expression is true when its result is nonempty and contains only nonzero elements logical or real numeric. Otherwise, the expression is false.

The Objective-C for loop described previously works well when you know in advance how many times a particular task needs to be repeated in a program. There will, however, be instances where code needs to be repeated until a certain condition is met, with no way of knowing in advance how many repetitions are going to be needed to meet that criteria. To address this need, Objective-C provides the while loop yet another construct inherited by Objective-C from the C Programming Language.
