Instance variable: Overview & Examples

In class-based, object-oriented programming, an instance variable is a variable defined in a class (i.e., a member variable), for which each instantiated object of the class has a separate copy, or instance. An instance variable has similarities with a class variable, but is non-static. In C++ or Java language, an instance variable is a variable which is…
