Question

If a member variable is declared ______________, all objects of that class share that variable.

Short answer

Answer: The keyword used to declare a member variable shared by all objects of a class is `static`.

Step-by-step solution

Understanding class variables vs. instance variables

In object-oriented programming, there are two types of variables: class variables and instance variables. Instance variables are specific to each object created from the class and have independent values for different objects. On the other hand, class variables are shared among all objects of the class, meaning that there is only one copy of the variable that is common to all instances of the class.

Identifying the keyword for class variables

The keyword used to declare class variables varies depending on the programming language being used. In most languages, class variables are declared using one of the following keywords: `static`, `class`, or `shared`.

Answering the given question

According to the given exercise, we need to fill the blank. "If a member variable is declared ______________, all objects of that class share that variable." The correct keyword to fill in the blank is 'static'. Therefore, the complete statement is: If a member variable is declared `static`, all objects of that class share that variable.
