There are two statements associated with

loops - break and continue. When a break

is encountered inside a loop, program control is transferred outside of it. So,

you use a break within a loop when you want to stop the loop execution at that

instant.

For instance, let’s

suppose you want to find out and print the first occurring multiple of 19

between two given numbers n1 and n2. Here’s what you will do:

int found = 0;  /* a flag to indicate whether multiple found
or not */
for (i=n1; i<=n2; ++i)
  if (i % 19 == 0){
        found=1;    /* setting flag to 1 */
        break;       /* multiple of 19 found; don’t look further */
  }
  if (found)
       printf("%d is the first multiple of 19 between %d and %d.\n", i, n1, n2);
 else 
       printf("There is no multiple of 19 between %d and %d.\n", n1,n2);
