Re: [Dev-C++] FunctionCalling()

[Daniel G. <sp...@ho...>]

You have to use forward declaration.

At the moment, when the function is called the compiler says
"what's this? functionTwo()? I don't know about that"

Either write out your functions before your main function, like

#include <iostream.h>

int FunctionTwo( int Input )
{
   Input = 365;
   return Input;
}

int main()
{
   int Input = 0;
   FunctionTwo( Input );
   cout << "End";
   return 0;
}

Or type them all out in to a header file, then #include it.

// in the header file (Functions.h)

int FunctionTwo( int Input )
{
   Input = 365;
   return Input;
}


// in the main (.cpp) file
#include <iostream.h>
#include "Functions.h"


int main()
{
   int Input = 0;
   FunctionTwo( Input );
   cout << "End";
   return 0;
}


P.S. I know that's not the greatest example of coding, but I'm keeping it 
simple as I got confused by examples when I started.

If you need help, post again!
