 Repetition Definition:

One or more instruction repeated for certain amount of time.

Number of repetition can be predefined (hard-coded in program) or defined later at run time.

Repetition/looping operation: 

–for 

–while 

–do-while

  

1) Repetition: For

• Infinite Loop

Loop with no stop condition can use “for-loop” by removing all parameters (exp1, exp2, exp3). To end the loop use break.

• Nested Loop

Loop in a loop. The repetition operation will start from the inner side loop.

2) Repetition: While

• exp is Boolean expression. It will result in true (not zero) or false (equal to zero).

• Statement will be executed while the exp is not equal to zero.

• exp evaluation is done before the statements executed
3) Repetiton: Do while 

•Syntax :

do{ 

    < statements >; 

} while(exp);

•Keep executing while exp is true

•exp evaluation done after executing the statement(s)
