Why are the addresses different (c++)?

Question

C++ / C#

When upgrading a project from VS2010 to VS2012, I encountered the following issue:

wchar_t var1[MAX_PATH];
wchar_t* tmpChar = var1;

The addresses are the same if the variables are within the scope of the method. If we have a situation, for example:

config.hpp
      static wchar_t var1[MAX_PATH];
main.cpp
     int main() {
          wchar_t* tmpChar = var1;
          return 0;
     }

then the addresses will be different (although the values ​​will be the same if var1 were defined). how to make it so that in the second case the addresses are the same?

Answer 1

static wchar_t
Each time the file is included, it creates its own copy of the var1 variable. Do it humanly, without static and with a declaration in the header and an implementation in the implementation file, and you will have one address.
