While Loop C Program

Introduction C while loop statement The C while loop statement allows you to execute a code block repeatedly based on a condition checked at the beginning of each iteration. Here's the syntax of the while loop statement while expression statement Code language C cpp How it works The while statement first evaluates the expression.

Working of while Loop. Let's understand the working of while loop in C using the flowchart given below flowchart for while loop . We can understand the working of the while loop by looking at the above flowchart STEP 1 When the program first comes to the loop, the test condition will be evaluated.

In programming, loops are used to repeat a block of code until a specified condition is met. C programming has three types of loops. for loop while loop dowhile loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop.

How while loop works? Simplicity of while loop exists in its working mechanism. while loop works in two steps. Initially program control is received by condition block. It contains set of relational and logical expressions. If result of the conditional expression is 1 true then while transfers program control to

Guess the output of this while loop. include ltstdio.hgt int main int var1 while var lt2 printfquotd quot, var The program is an example of infinite while loop. Since the value of the variable var is same there is no or - operator used on this variable, inside the body of loop the condition varlt2 will be true forever and the

While Loop Syntax in C Language A while loop in C language is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. Following is the syntax to use the while loop in C Programming Language. Here, Condition The loop starts with the evaluation of a condition. This condition is a boolean

While Loop in C Programming Example. This program allows the user to enter an integer value below 10. By using this value, the compiler will add those values up to 10. In this while loop example, the User will enter any value below 10, and the total variable is initialized to 0. Next, the user-entered value will assign to the number variable.

The while loop is one of the most frequently used types of loops in C. The other looping keywords in C are for and do-while. The while loop is often called the entry verified loop, whereas the do-while loop is an exit verified loop. The for loop, on the other hand, is an automatic loop. Syntax of C while Loop

In C language, while loops are used when you do not know how many times a particular loop will execute. For loops are used when you know previously how many times a loop will execute. While loops are common where the program runs in an infinite loop until the user terminates it or while a specific input device will keep sending it input, the while statement will continue to execute.
