Using multiple .cpp files for programs

Alright, this is what I'm trying to do:

I want the main.cpp to have a menu for example saying for example:

Menu:
1. This is the first thing
2. This is the second thing

Then a simple input option and then I if they for example choose option one I want them to be redirected to.. let's say Option1.cpp and then when they're done there it needs to return you to main.cpp

Please help me out doing this, cheers!

Do you know how to use functions? You don't redirect execution flow to another file, but call functions that are implemented in different cpp files and are available to main.cpp through declarations in header files (*.h, *.hpp).

Not quite sure what you mean..

Like #include <Option1.h> or what?

There's a FAQ on writing multi-file projects.

Suppose you had all in one file:

Code:

//declarations - go into headers
void option1(); 
void option2();

int main()
{
    option1();
    option2();
}

//implementations may go into a separate cpp file
void option1()
{
    //implementation
}

void option2()
{
   //implementation
}

A typical header might look like this:

Code:

//options.h

//inclusion guards
#ifndef OPTIONS_H
#define OPTIONS_H

void option1();
void option2();

#endif

An implementation file which needs to know about these functions (to implement or use them), includes the header

Code:

#include "header.h"

Each cpp file needs to be compiled and linked (easily achieved if they all belong to the project).

Alright, thanks alot.
