Program control : Repitition

Repitition means one or more instruction repeated for certain amount of time.

There are 3 kinds of it :

• for
• while
• do-while

Repitition : FOR

Here it is the example of using 'for' to print out number 1 to 10

#include<stdio.h>

int main(){

    int x;

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

    return 0;

}

And here it is the example of using 'for' to print out number 10 to 1

#include<stdio.h>

{

    int x;

    for( x = 10 ;  x >= 10 ;  x-- ) printf("%d\n", x );

    return 0;

}

Infinite loop => looping that done until countless times.

Repitition : WHILE
Example :
#include<stdio.h>
int main(){
int counter = 1;

while ( counter <= 10 ) {

     printf( "%d\n", counter );

     ++counter;

return 0;

}

Repitition : DO-WHILE
Example :
#include<stdio.h>
int main(){

int counter=0;

do {

     printf( "%d", counter );

  ++counter;

} while (counter <= 10);

return 0;
}


Break vs Continue
Break => is to force finish the loop
Example :
#include<stdio.h>
int main(){
int x = 1;
while (x<=10) {
printf("%d\n", x);
x++;
break;
}
return 0;


}

Continue => skip all the rest of statement inside a repetition, and continue normally to the next loop.
Example :

#include <stdio.h>

int main() {

        int x;

        for(x=1; x<=10; x++) {

      if (x == 5) continue;

       printf("%d ", x);

        }

        return 0;

}
