C – break statement

  1. It is used to quickly come out of a loop. When a break statement is encountered inside the loop, control directly comes out of the loop and the loop terminates. It is used with if statement whenever it is used inside a loop.
  2. It can also be used in switch case control structure. Whenever it is encountered in a switch-case block, the control comes out of the switch-case (see example below).

Syntax:

break;

Example – Use of break in a while loop

#include <stdio.h>
int main()
{
     int num =0;
     while(num<=100)
     {
        printf("value of variable num is: %d\n", num);
        if (num==2)
        {
            break;
        }
        num++;
     }
     printf("Out of while-loop");
     return 0;
}
value of variable num is: 0
value of variable num is: 1
value of variable num is: 2
Out of while-loop

Example – Use of break in a for loop

#include <stdio.h>
int main()
{
      int var;
      for (var =100; var>=10; var --)
      {
           printf("var: %d\n", var);
           if (var==99)
           {
               break;
           }
      }
     printf("Out of for-loop");
     return 0;
}

Output:

var: 100
var: 99
Out of for - loop

Example – Use of break statement in switch-case

#include <stdio.h>
int main()
{
      int num;
      printf("Enter value of num:");
      scanf("%d",&num);
      switch (num)
      {
          case 1:
             printf("You have entered value 1\n");
             break;
          case 2:
             printf("You have entered value 2\n");
             break;
          case 3:
             printf("You have entered value 3\n");
             break;
          default:
             printf("Input value is other than 1,2 & 3 ");
     }
     return 0;
}

Output:

Enter value of num:2
You have entered value 2
