Norwegian / Norsk The syntax of while loop in C language is given below: As we have declared the value of i=1, which is called initialization. How it works: In line 5, we have declared a variable i and initialized it to 1.First, the condition (i < 100) is checked, if it is true. Next, it enters into the Do While loop. The do-while loop can be described as an upside-down while loop. • Repeat these statements while the number n is not prime. Next increment i by one i.e. A while loop is a pre-tested loop. And it will continue up to the condition is false. Now everything is about simple logic. It will execute the group of statements inside the C Programming loop. Syntax of while loop in C programming language is as follows: while (condition) { statements; } It is an entry-controlled loop. Once the expression becomes false, the loop terminates. However, there are a few differences between these three.
