break statement

break statement is used to come out of the loop instantly. As soon as the break statement is encountered from within a loop, the loop iterations stops there and control returns from the loop immediately to the first statement after the loop.

The syntax of the break statement is as follows:

break;    

#include stdio.h;
#include conio.h;
void main()
{  
    int n;  
    for(n = 1; n5; n++)  
    {  
        printf("%d ",n);  
        if(n == 3)  
        break;  
    }  
    printf("last value of loop is = %d",n);  
    getch();
}  

Output

1 2 3 last value of loop is n = 3

This can also be used in switch case control structure. Whenever it is encountered in switch-case block, the control comes out of the switch-case.

#include stdio.h
#include conio.h
void main()
{  
    int m;
      printf("Enter value of m=");
      scanf("%d",&m);
      switch (m)
      {
          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 ");
     }
     getch();
}  

Output

Enter value of m=1
You have entered value 1
