  1. Initialization Expressions — It initializes the loop control variable and it is given outside the while loop before the beginning of the loop.
  2. Test Expression — If its truth value is true then the loop-body gets executed otherwise not.
  3. The Body of the Loop — It is the set of statements that are executed repeatedly in loop.
