Latest Answer : In C, we can use only inbuilt data types for program needs but from C++ we can create userdefined datatypes in form of classes. Classes wrap datamembers and member functions that operate on datamembers together. ... Object is a software bundle of variables and related methods. Objects have state and behavior. Latest Answer : An object is an instance of the class through which we can access the methods and class variables ...
