While Loop In C Language

In C, a while loop is a control flow statement that allows you to repeatedly execute a block of code as long as a certain condition is true. The syntax for a while loop is as follows:

Copy code

while (condition) {    // code to be executed }

The condition is a boolean expression that is evaluated before each iteration of the loop. If the condition is true, the code inside the loop is executed, and the process is repeated. If the condition is false, the loop exits and the program execution continues with the next statement after the loop.

For example, the following code uses a while loop to print the numbers from 1 to 10:

Copy code

int i = 1; while (i <= 10) {    printf("%d ", i);    i++; }

The loop variable i is initialized to 1, then it's compared with 10 in the while loop, and as long as it's less than or equal to 10 the loop will execute, printing the value of i and then increment it.

It is important to make sure that the condition in the while loop eventually becomes false, otherwise the loop will run indefinitely, causing an infinite loop.

Also, it's important to take care of the variables that are used inside the while loop, if they're not modified inside the loop, the loop will be infinite.
