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.
Difference Between For loop and While loop (With Table)
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.
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. Use a while loop to calculate factorial Count the number of lines of code in the file magic. Skip blank lines and comments using a continue statement.

What is the difference between while loop and do while loop. I used to think both are completely same. Then I came across following piece of code:. It gives a blank screen. It do not work.
do while loop in C
In this tutorial, you will learn to create while and do In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do.. To learn more about test expression when the test expression is evaluated to true and false , check out relational and logical operators. The do.. The body of do
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. Entry controlled loop 2.
C Loops: For, While, Do While, Looping Statements with Example
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. Furthermore, the while loop is known as the entry-controlled loop.
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.
