Calling a user-defined function in C++

I am trying to call a function that I created and placed in a .h file. When the function is in my program, it works great. However, when I place the function in the .h file and call to it, I get "undefined reference" errors in the compile. I'm not certain of the syntax for defining a function in the .h file, which is probably the problem.

I am looking for an example of a function call to a user-defined function and .h file.

I am using TextPad to write the code and GNU to complile on a 2000 machine.

Attached is a zip file with the program (cgrade.cpp), the .h file (myfuncts.h) and the cpp file for the .h file (myfuncts.cpp).

Any help or suggestions would be greatly appreciated.

Thanks,

Brian

example, in example.h u have callme () function.

so in your main .cpp:

#include <example.h>


in the code where u want it


callme ();


Thats what i do, in VC++

replace the top of your program file with:


#include <iostream>
#include "myfuncts.h"
#include "myfuncts.cpp"
#include <string>

//double weighted_avg(double, double, double);
//string letter_grade(double);

The reason is that unless you compile "myfuncts.cpp" and then include the ".o" file in the build, you won't be able to reference the functions. Also, you can put the functions in the ".h" file instead, if you'd like.

Sebastiani,

Thank you very much. It seems like such a simple solution now, but thank you. It's working just fine now.
