2. What is Iteration? Iteration construct means repetition of set of statements depending upon a condition test. Till the time of condition is true. ( or false depending upon the loop). A set of statements are repeated again and again. As soon as the condition become false (or true), the repetition stops. The iteration condition is also called ”Looping Statement ” . Idli

5. The for Loop

6. The for Loop In  computer science a  for-loop  (or simply  for loop ) is a  programming language control statement for specifying iteration, which allows code to be executed repeatedly. Syntax for ( ForInit ; ForExpression ; PostExpression ) Action Example for ( int i = 0; i < 3; ++ i ) { cout << " i is " << i << endl ; }

9. The while Loop

10. The while Loop In most computer programming languages, a  while loop  is a  control flow statement that allows code to be executed repeatedly based on a given boolean condition. The  while  loop can be thought of as a repeating if statement . Syntax

13. The do-while Loop

14. The do-while Loop  a  do while loop  is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given  boolean condition at the end of the block . Syntax do Action while ( Expression )
