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.
