  • While loop evaluates the conditions inside the brackets.
  • If the condition returns true, the statements inside the while loop body will be executed.
  • Condition inside the while loop is executed once again.
  • This process goes on until the condition in the while loop becomes false.
  • Once the condition is false, while loop terminates.

    • Syntax of While loop

    while (testExpression) {
      // the body of the loop 
    }

    Sample Code

    #include <stdio.h>

        printf("%d\n", i);
        ++i;
