What will be the output of the following C program?

#include <stdio.h>

int main(void) {
    int n = 2;
    switch (n) {
        case 1: printf("A");
        case 2: printf("B");
        case 3: printf("C");
                break;
        default: printf("D");
    }
    return 0;
}
  1. B
  2. BCD
  3. ABC
  4. BC
Answer and explanation

Answer: D. BC

Explanation: Control jumps to case 2 and prints B. There is no break, so it falls through to case 3 and prints C, then the break exits the switch before default.
