How to call function from c++ file from one project to another (Visual Studio 2005)

|_ProjectA >> amain.c

|_ProjectB >> bmain.c

/*amain.c*/
#include <iostream>
using namespace std;
int main()
{
cout << add(10,20);
return 0;
}

/*bmain.c*/
#include <iostream>
using namespace std;
int add(int a, int b);
int main()
{
return 0;
}
int add(int a, int b)
{
return a + b;
}

You can't not with your code structured like that.

The solution would be to have a 3rd project ProjectC that compiles to a static or dynamic library that contains add and then make both ProjectA and ProjectB depend upon ProjectC.

Banfa, how to do the things your are saying?

[weaknessforcats]

Why does bmain.c have a main() in it?

Why not just name the function add() ??

Then you add bmain.c as a source file in Project A and use a function prototype in Project A.

Or:

Have Project B produce a DLL that you use in Project A.
