Thread: Extern functions?

Hi all,
I have these .CPP files ("Main.cpp" and "RandomFunction.cpp"):

Code:

/*
 * "Main.cpp"
 */

#include "RandomFunction.cpp"

int main()
{
    randomFunction();
}

Code:

/*
 * "RandomFunction.cpp"
 */

void randomFunction()
{
    // Do some stuff
}

But when I launch the program, the compiler gives me a linker error: "RandomFunction.obj : error LNK2005: "void __cdecl randomFunction(void)" (?randomFunction@@YAXXZ) already defined in Main.obj"

So how should I rewrite the code to fix the linker error (I think I should define somewhere the extern function)?


Thanks.
