Hi all,

I am new to Linux and c++ programming.

What I am trying to do is to declare an object in a .cpp and be able to access it from main.At the moment my code creates a new object in the ena.cpp and cannot use the one from the alpha.cpp. How can i access the object from alpha.cpp (bita.dio=6) from the main (ena.cpp).

Many thanks in advance.

ena.cpp
Qt Code: 
  1. #include <iostream>
  2. #include "alpha.h"
  3. #include "bita.h"  
  4. using namespace std;
  5.  
  6. int main() 
  7. {
  8.   A ob(4);
  9.   B bita;//<this creates a new project which is irrelevant of the one i need to pass from alpha.cpp
  10.   			// i need to remove that
  11.   cout << ob.get_a();
  12.   cout << bita.dio;//<-- This currently outputs 2 (and not 6 as i want)
  13.     //cout << par;
  14.   return 0;
  15. }
