Consider a class named Calculator with typical four specific functionalities i.e. addition, subtraction, multiplication, and division. Implement these functionalities as four functions with two parameters. It is also required to overload all these functions for int and double data types. In the main function, create an object of class Calculator and invoke its member functions while passing parameters of int and double type.
Assignment Question :
#include <iostream>
using namespace std;
class Animal {
protected:
int length, height;
public:
void set_values (int l, int h)
{ length = l; height = h; }
virtual int cage_size (void) =0;
};
A. Based on the above class definition, provide the derived classes below that will override the function cage_size from the base class Animal:
i.Elephant, cage_size = 1.5 x length x height
ii.Giraffe, cage_size = 2.5 x length x height
B. Write the complete main () function that will create the object Elephant and Giraffe. Insert their length and height to calculate their cage_size.
Note: A virtual function is a member function which is declared within a base class and is expected to be re-defined (overridden) by a derived class.
Given the Class Definition for ClockType discussed extensively in class, write what
would have to be added to the FUNCTION DEFINITION for the Class ClockType to
overload the “= =”, i.e., the comparison “equal-equal sign,” here:
NOTE: In other words, WHAT WOULD BE ADDED TO THE CLASS DEFINITION ONLY?
Note: ThePrivate Members are:
int hr; // contains the hours
int min; // contains the minutes
int sec; // contains the seconds
