Program Control: Repetition


        Repetition is the action of repeating something that has already been processed. The most common repetition in c are: if, if-else, else-if, while, do-while, for, and switch-case-break.

1. If

     The syntax of "If" repetition :
   
     if ( condition ) {
          statement;
     }

2. If-else

     The syntax of "If-else" repetition :

     if ( condition1 ) {
          statement1;
   
     else {
          statement2;
     }

3. Else-if

     The syntax of "Else-if" repetition :

     if ( condition1 ) {
          statement1;

     else if ( condition2 ) {
          statement2;
 
     else {
          statement3;
     }

4. While

     The syntax of "While" repetition :

     statement;
     while ( condition );

5. Do-while

     The syntax of "Do-while" repetition :

     do {
          statement;
     } while ( condition );

6. For

     The syntax of "For" repetition :

     for ( exp1, exp2, exp3 ) {
          statement;
     }

7. Switch-case-break

     The syntax of "Switch-case-break" repetition :

     switch ( exp ) {

          case exp1 :
               statement1;
               break;

          case exp2 :
               statement2;
               break;

          default:
               statement3;
     }
