Wells Fargo Encapsulation Problems with Solutions Quiz-1

Both have the same properties with regard to an object of the class.

Private members cannot be directly accessed, while protected members can be directly accessed.

Protected members cannot be accessed by member functions, while private members can be accessed by member functions.

Private and protected members are same in all regards

private members of a class like any private method can only be accessed by any other method in this class,not from a outside class method. But in case of any protected method the method can be accessed by a outside class method if the class is sub class of the accessed method class.

The data and operation for an object are defined and fixed.

Data of an object is encapsulated in its class

Data is hidden for an object

A class can have multiple objects

He should define a third member function (public) which multiplies the two numbers.

He should define member functions (public) to return value of both the integers and then multiply them in his code. By returning the values, he can in future do any operation on them giving extensibility to the code.
