ex1305

#include <stdio.h>
#include <ctype.h>

int main()
{
    char answer;

    printf("Would you like to blow up the moon? ");
    scanf("%c",&answer);
    answer = toupper(answer);
    if(answer=='Y')
        puts("BOOM!");
    else if(answer=='N')
        puts("The moon is safe");
    else
        puts("Indecision can be fatal!");
    return(0);
}

Would you like to blow up the moon? 8
Indecision can be fatal!

Notes

* The obvious solution is to construct an if-else if-else structure. Even so, you'd get points if you constructed a switch-case structure instead. Either method solves the problem.

* If you'd like the practice, construct a switch-case solution.

* Single characters literals in C are enclosed in single quotes.
