Global variables. Maybe im wrong… /u/9acca9 Python Education

If i dont recall bad i always hear and read “Dont user global variables!!!” or “yes, you can but try to avoid!”

Now im seeing some codes for Arduino that are writing in C++ (yep, another language)… and here i see that people use a lot of global variables without problems.

This is just because is c++ or because is arduino, or i get wrong the idea about global variables?

Thanks!
