You have to define and initialize a static member variable somewhere in your code at the top level (outside of any function) the same way you define and initialize a global variable The compiler will ensure that the initialization is done before your program starts executing at the main function

How to initialize private static member variables in C++?
Here we will see how to initialize the private static member variables initialization in C++. We can put static members (Functions or Variables) in C++ classes. For the static variables, we have to initialize them after defining the class. To initialize we have to use the class name then scope resolution operator (::), then the variable name.
Can a non-static variable be initialized outside a class in C++?
@nn0p not yet , but non-static private variables initialization outside Class doesn't makes any sense in Cpp. Since C++17, static members may be defined in the header with the inline keyword. "A static data member may be declared inline.
What is the Default initialization value of a static variable in C?
· The default initialization value of a static variable is zero, even if it is not assigned, which is not the case in a local variable. · It is mandatory to initialize the static variable using the static keyword in C else it will return an error. · The static variable is only initialized the first time when a function is called.
How to initialize static variables in a class in PHP?
Regarding the initialization of complex static variables in a class, you can emulate a static constructor by creating a static function named something like init () and calling it immediately after the class definition. self::$b = self::$a . " World!"; Inheritance with the static elements is a nightmare in php. Consider the following code:
