Choice B No choice
Choice A

Answer 1

The correct answer is option 2: Choice A
Choice B

Key Points

Given code:

char inchar = 'A';
switch (inchar)
{
    case 'A':
        printf("Choice A\n");
    case 'B':
        printf("Choice B");
    case 'C':
    case 'D':
    case 'E':
        break;
    default:
        printf("No Choice");
}

Explanation:
- The value of inchar is 'A'.
- The control enters case 'A' and executes printf("Choice A\n");
- No break after case 'A', so execution continues to case 'B' and prints Choice B
- After that, it reaches case 'C' ... case 'E' and hits a break;, which stops the switch.
- default is not reached since execution already matched case 'A'.

Final Output:

Choice A
Choice B

Hence, the correct answer is: option 2: Choice A
Choice B
