Re: [Dev-C++] Problem compiling a simple student grading program

[Per W. <pw...@ia...>]

Make sure the compiler knows that you have multiple grade() functions
before you make the call. At the point of error, the compiler only knows
about the grade function that takes a reference to a struct, and it see
you send three floating-point numbers. That makes the compiler unhappy.

With function prototypes before the call, the compiler will know which
grade() function to use.
