Help me translate these compile errors

The jpegs are the screenshots of the compiler errors, incase you don't use dev-c and the errors say something different on your compiler. The third attachment is the complete code incase it's needed.

I know these are probably simple errors but I'm just not getting it!

I appreciate any insight.

------------------------
I've fixed my errors in the if..else statement.

I called my functions instead of defining them.

Now I am getting an error with

int getPin (int pin, int attempts)

I only want to return attempts into my main. Is this the correct way to write the function?

You're using the same name to be more than one thing.
You're declaring function prototypes, not calling functions (and using full braces would definitely help).
