Ugh, I need help with this C++ programming homework.

Homework 8: Uses of Static

Static is a C++ keyword with several meanings

Steps:

1. A static local variable has a lifetime of the entire program. This means it keeps its value between calls to the function it is in. It is initialized once, at the beginning of the program.
2. A static global variable or function is visible only in the file it is declared in (anonymous namespace preferred).
3. A static member variable in a class exists only once for the entire class.
4. A static member function can be called without using an object of the class, and can only access static member variables.

Write code to demonstrate meanings 1, 3, and 4.

Ensure that comments exist in main.cpp that clearly indicate which step is being implemented.
