Creating and Managing Global Variables

Creating and Managing Global Variables

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.
