#include <stdio.h>
void main()
{
    int a = 2;
    switch (a)
    {
        case 4: printf("A");
        break;
        case 3: printf("B");
        default : printf("C");
        case 1 : printf("D");
        break;
        case 5 : printf("E");
    }
}

(A) Printed: A
(B) Printed: E
(C) Printed: CD
(D) None

Answer: (C)
Explanation: In switch statement default should be at mentioned after all the switch cases. In this case, it gets executed in between and all cases after default are executed before a break statement.

#include <stdio.h>
void main()
{
    int a = 2;
    switch (a)
    {
        case 4: printf("A");
        break;
        case 3: printf("B");
        default : printf("C");
        case 1 : printf("D");
        break;
        case 5 : printf("E");
    }
}
