Answer to Question #192444 in C++ for Dunga

Question

Create a C++ program to demonstrate hierarchical inheritance to get square and cube of a number. Base class must calculate square of a number whilst base class 2 calculates cube of a number. The program must prompts the user as follows

Enter an integer number: 10

Square of 10 is: 100

Enter an integer number: 20

Cube of 10 is: 8000

#include <iostream>
using namespace std;

        int num;
    public:
        void getNumber(void)
        {
            cout << "Enter an integer number: ";
            cin  >> num;
        }
        
        int returnNumber(void)
        { return num; }
};

{
    public:
    int getSquare(void)
    {
        int num,sqr;

class Cube:public Number
{

    {
        int num,cube;
        num=returnNumber();

int main()

        Square objS;
        Cube objC;
        int sqr,cube;
