If statement to ask yes/no question

[epsilon tau]

Hi sorry if this has already been asked but I've looked and couldn't find it. I've been working on a program for my university work I want the program to repeat if the user answers yes to a question but the code I have written does not work and I can't see why.

  
char answer = '\0';

    printf("Would you like to calculate another price? Y/N: ");
    scanf("%c", &answer);

    if ( answer == 'Y' || answer == 'y' )
    {
        mn();
    }
    else
    {
        return 0;
    }

If you've been using other scanf formats, you typically have to write
scanf(" %c", &answer); // note leading space
to skip any whitespace, and thus read the next non-space character.

Also, using an if will only allow you to repeat once per if statement. I suspect you're calling your mn() function recursively to repeat this, which is not a good method, as it can use up all your stack space and crash your program. Use a loop. do while loops work well for user input:

do {
    calculate a price
    print "Repeat?"
    read answer
} while (answer == 'Y' || answer == 'y');

Thank you that worked perfectly
