C/Language Basics/For Break

Break a infinite loop

<source lang="cpp">

1. include <stdlib.h>
2. include <stdio.h>

int main(void) {

 for(;;)
   if(getchar()=="A") abort();
 return 0;

}

      </source>

indefinite loop and break

<source lang="cpp">

1. include <stdio.h>
2. include <ctype.h> /* For tolower() function */

void main() {

  char answer = "N";  /* Records yes or no to continue the loop */
  double total = 0.0; 
  double value = 10.0; /* Value entered                          */
  int count = 0;      /* Number of values entered               */
  printf("\nThis program calculates the average of"
                                      " any number of values.");
  /* Indefinite loop */
  for( ;; ) {
    total += value;                 /* Add value to total        */
    ++count;                        /* Increment count of values */
    /* check for more input */
    printf("Do you want to enter another value? (Y or N): ");
    scanf(" %c", &answer );   
    if( tolower(answer) == "n" )    
      break;                         /* Exit from the loop      */
  }
  /* output the average to 2 decimal places */
  printf ("\nThe average is %.2lf\n", total/count ); 

}

      </source>

Nested for loop and break

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int i, j;
 for( i = 0; i < 5; i++) {
   for(j = 0; j < 100; j++) {
     printf("%d", j);
     if(j == 5) 
         break;
   }
   printf("\n");
 }
 return 0;

}

      </source>

Use break in for loop to exit

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int i;
 for(i = 1; i < 100; i++) {
   printf("%d ", i);
   if(i == 10) 
       break; /* exit the for loop */
 }
 return 0;

}

      </source>

Use break to terminate a for loop

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int t;
 for(t = 0; t < 100; t++) {
    printf("%d ", t);
    if(t == 11) 
       break;
 }
 return 0;

}

      </source>
