I wanted to check by placing default anywhere in the switch. It should print the default printf statement as no case label is matching & after that default case is checked in the switch. But it's showing the above error.

#include <stdio.h>

int main(void) {
    // your code goes here
    char ch='g';
    switch(ch){
        default: printf("Success!\n");
        case 'v':
        case 'h':
    }
    return 0;
}
