Thread: Help With If/Else If Statement

Well, I'm new to C, previously a programmer in PHP. Sorry if I'm making any obvious mistakes.

Anyways, I'm writing a simple CLI program that answers to Y/N.

If I type in Y, everything works as expected. However, when I type in N, it executes both the else if, and the else conditionals.

(Y/N)?: N
Wrong answer...
(Y/N)?: Please type Y or N.
(Y/N)?:

When I type in something random, the else is executed for every character inputted. No idea why:

(Y/N)?: asdf
Please type Y or N.
(Y/N)?: Please type Y or N.
(Y/N)?: Please type Y or N.
(Y/N)?: Please type Y or N.
(Y/N)?: Please type Y or N.
(Y/N)?:

Here is the code:

Code:

#include <stdio.h>


void yesno() {


    char choice;
printf("(Y/N)?: ");
    scanf("%c", &choice);

    if (choice == 'Y') {
        printf("<333");
    }
    else if (choice == 'N') {
printf("Wrong answer...\n");
        yesno();
    }
    else {
printf("Please type Y or N.\n");
        yesno();
    }
}


int main()
{
//ask_question();

    yesno();

    fflush(stdin);
    getchar();

    return 0;
}

Again, sorry if I did something really stupid or obvious.

Thanks tons!

Code:

fflush(stdin);
