These variables are usually created when we create an object and are destroyed when the object is destroyed. A global static variable in c++ is a static variable declared outside of any class or function The second difference can be useful to avoid the static intialisation order fiasco, where global variables can be accessed before they're initialised

By replacing the global variable with a function that returns a reference to a local static variable, you can guarantee that it's initialised before anything accesses it.
Using the static keyword on a local variable changes its duration from automatic duration to static duration.
So, oop defines another kind of member variable, called a class variable This kind of member variable has the same value across all objects of the class Totemps, then, must be made a class variable C++ designates class variables by the keyword static, and designates instance variables by the lack of that keyword
Java uses this syntax too. A global variable is declared outside of the method, but inside of a class, making it accessible to all methods of the class Automatically initialized with default values Stored in heap (instance) or method area (static)
Every variable in c++ has two features
Type specifies the type of data that can be stored in a variable And, storage class controls two different properties of a variable Lifetime (determines how long a variable can exist) and scope (determines which part of the program can access it). No, there's no difference between c and c++ in this respect
Read this so answer about what static means in a c program In c++ there are a couple of other meanings related to the use of static for class variables (instead of instance variables)
