Repetition Definition

        Pengulagan satu atau lebih pada suatu kondisi tertentu.

          Repetition/looping can use 3 types of operation=

-        - for

-        - while

-        - do-while

              for explanation

 

•        Syntax:

for(exp 1; exp2; exp3) statement;

or:

for(exp1; exp2; exp3){

                        statement1;

                        statement2;

                        …….

 }

exp1 :  initialization

exp2 :  conditional

exp3 :  increment or decrement 

exp1, exp2 and exp3 are optional

exp1 and exp3 can consist of several expression separated with comma

•        Flow Chart of for

•        Sample of for with flow chart

for (x=1; x <= 10; x++) printf(“%d\n”, x);

 

•        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.

int x, y; for (x=1;x<=5;x++)      for (y=5; y>=1; y--)            printf(”%d %d ”,x,y);

FOR C ==>

for (int x=1;x<=5;x++)      for (int y=5; y>=1; y--)            printf(”%d %d ”,x,y);

FOR C++ ==>
