Comparing two characters

[tassa]

Hello,

I'm new to C++ and I was wondering how to compare two characters... Right now I'm using:

    char *o;
    printf("Try Again? (n/y): ");
    scanf("%c", &o);
    int res = strcmp(o,"y");
    if (res == 0){
        system("CLS");
        goto calculate;
        }
    else if (res < 0 || res > 0) {
        printf("\n\n%c\n",o);
        printf("See ya!...\n");
        }

But it's not working, because it doesn't execute the command after the first if (assuming both chars match).

Thanks in advance!

Because strcmp needs to be 2 strings... Not a string and a character. To compare 2 characters, you can do it directly (use ==).

So just try this:

char o;
printf("Try Again? (n/y): ");
scanf("%c", &o);
if (o == 'y') {
system("CLS");
goto calculate;
}
else {
printf("\n\n%c\n",o);
printf("See ya!...\n");
}

Thanks! I'll try that!
