The explanation is very clear and useful. Thanks. Helped me a lot to understand the static keyword. The explanation is very clear and useful. Thanks.

The discussion on file scoped variables on this tutorial is all of 6 sentences, the last of which explicitly discourages their use (in previous tutorials, I talk about the downsides of global variables). The rest of this tutorial discusses fixed duration variables, which have a lot of utility in C++. Most of these earlier tutorials cover topics that C++ inherits from C. In my opinion, it's highly useful for developing programmers have a solid understanding of these concepts before trying to understand things like classes, inheritance, and templates.

There are way better encapsulation mechanisms in C++. This tutorial looks like a s/printf/cout/ approach at learning C++. It's actually teaching C with C++ syntax. static at the file scope is a good idea in C, but it’s very bad practice in C++ (I heard it’s even deprecated).

For example, each time IncrementAndPrint() is called, s_nValue comes back into scope with it's previous value. This allows you to have a variable that keeps track of it's value between calls without exposing that variable to other functions (which is dangerous, because they might change it).
