Sometimes, you can't avoid declaring global variables in C++. However, should you prefer not to mix C++ with C code techniques, try the following:

• Create a global class and add your global variables.

  
  class MY_GLOBALS
  {
     static int global_var1;
     static int global_var2;
     .
     .
     .
  };
  

• Next, access the data member of MY_GLOBALS:

  
  MY_GLOBALS::global_var1 = 10;
  some_var = MY_GLOBALS::global_var1;
  

This helps you avoid declaring external variables. Moreover, you keep all your global variables in one class instead of scattering them throughout different files.
