Program Control : Repetition (10 October 2018)

Definition of Repetition
   => 1 or more instruction repeated for certain amount of time.
   => Number of repetition can be predefined or defined later when running the program.


Repetition or Looping operation consist of :
1. For
2. While
3. Do - While


For = Syntax : for(exp1; exp2; exp3) statement;
                         or
                         for(exp1; exp2; exp3){
                                statement1;
                                statement2;
                         }

     exp1 : initialization
     exp2 : conditional
     exp3 : increment/decrement
     statement : what the program should do if condition for "For" true

     Example :
     void reverse(char ss[]){
            int c, i, j;
            for(i=0, j=strlen(ss)-1; i<j; i++; j--){
                 c=ss[i];
                 ss[i]=ss[j];
                 ss[j]=c;
             }
      }

      //Reverse used to reverse words from a string. Example :Hello => Olleh
 

      > Infinite Loop
          A loop without any stop condition by removing all parameters.
          To stop the loop, click the box and then Ctrl+C to break the loop.
     > Nested Loop
         A loop inside a loop. The loop will start from the inner side loop.
