Break Statement in C Programming



Previous Next


In C programming, the break statement is used to exit a loop prematurely or to exit a switch statement.

Example 1: Break in a Loop

#include <stdio.h>

int main() {
    int i;
    for (i = 1; i <= 10; i++) {
        if (i == 5) {
            break; // Exit the loop when i is 5
        }
        printf("%d ", i);
    }
    return 0;
}
Output: 
1 2 3 4

In this example, the program will print numbers from 1 to 4 and then exit the loop when i becomes 5 because of the break statement.



Example 2: Break in a Switch Statement

#include <stdio.h>

int main() {
    int choice = 2;
    switch (choice) {
        case 1:
            printf("Option 1 selected\n");
            break;
        case 2:
            printf("Option 2 selected\n");
            break; // Exit the switch statement after printing this line
        case 3:
            printf("Option 3 selected\n");
            break;
        default:
            printf("Invalid choice\n");
    }
    return 0;
}
Output: 
Option 2 selected

In this example, because choice is set to 2, the program will print "Option 2 selected" and then exit the switch statement due to the break statement.
