What does a private static variable do?
Private static methods serve as utility methods within a class.
Since they are not tied to any instance, they can be called using the class name without the need for an object.
Making them private ensures that they are not accessible from outside the class, maintaining encapsulation.What is a static variable in C?
A static variable possesses the property of preserving its actual value even after it is out of its scope.
Thus, the static variables are able to preserve their previous value according to their previous scope, and one doesn't need to initialize them again in the case of a new scope.Inside of a class, you can refer to its static variables simply by using their names.
But to access them from another class, you need to write the name of the class before the name of the static variable.
The variable is private .
It is not visible outside the class.
Can static member variables be private?
Static member variables
It is essentially a global variable, but its name is contained inside a class scope, so it goes with the class instead of being known everywhere in the program.
Such a member variable can be made private to a class, meaning that only member functions can access it.
