To determine the mileage, you need to perform a calculation using the distance driven and the amount of fuel used. In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state ( member variables) and implementations of behavior (member functions or methods ). credit by exam that is accepted by over 1,500 colleges and universities. The class is a model or blueprint or prototype of an object that defines or specifies all the properties of the objects.
