Beginner C++ question

hmm...i think i might get your drift

in file1.cpp make something like

extern int somenumber;

then you should be able to call it from another file


or maybe you should just use the #include "file.h" directive

I tried the #include "file.h" directive but i get variable already declared errors but i''ll try the extern keyword.

I had that poblem too:

first create a header file for your variables, something like
"MyVars.h"

in your main module, write
#include "myvars.h"

This is the code for your MyVars header:

#ifndef myvarsh_abdg23 //this prevents "alredy defined" errors #define myvarsh_abdg23 // use any string after ifndef extern int myfirstvar; // your variable #endif // this is at end of ile, after all code

Now, you should be able to use the myfirstvar integer variable in
your main module...

Good Luck with your programming,
