    • Your file ends in .cpp. You are asking for help in the C subforum.
    • You can only return one variable or value. You are attempting to return multiple variables in your scan() function.
    • The pointers in your scan() function are dangling pointers. You never initialized them.
    • Your program uses the scanf function directly.
    • There are multiple ways to scan in data. For example, using gets. But gets is not a "safe" function.
    • Using "goto" when not needed is generally seen as a poor programming habit.
    • conio.h isn't standard C. It's better to just use getchar to keep the console open.

    Yes, by using say, fscanf or sscanf, or by parsing the input yourself.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
