As long as the given condition stands true, the **While Loop** can be used to execute a set of statements repetitively. The While loop depends on the following:

* **Condition:** This controls the termination of while loop. If the condition becomes false, the while loop will terminate. 
* **Execution statements:** This completes the tasks assigned to the while loop.

# How it works

The **While loop** will first check the value of the *condition,* and if it is *true* then the statement (or multiple statements) will be executed once. 

Afterward, the condition will be evaluated *again* and if it stands true, the statements will be executed again, and so on. The While loop will only stop when the condition is found to be *false.*

# Example
The following code adds "3" to the answer until the answer becomes 30.

#include <stdio.h>
int main () {

   int answer=0; 

   //while loop
   while( answer != 30 ) {
      answer=answer+3; //statements to be executed
   }
   printf("value of answer = %d\n", answer);
   return 0;
}
