Write a program in C++ to display the cube of the number up to a given integer using class objects in object-oriented programming.

#include<iostream>
using namespace std;
class a
{
protected:
int n;
public:
int cube()
{
cout<<"enter the number :"<<endl;
cin>>n;
for(int i=0; i<n; i++)
{
cout<<" cube of "<<i<<" is "<<"="<<(i*i*i)<<endl;
}
}
};
int main()
{
a obj;
obj.cube();
}

#include<iostream>

using namespace std;

class a

{

protected:

int n;

public:

int cube()

{

cout<<"enter the number :"<<endl;

cin>>n;

for(int i=0; i<n; i++)

{

cout<<" cube of "<<i<<" is "<<"="<<(i*i*i)<<endl;

}

};

int main()

{

a obj;

obj.cube();

}

Output

enter the number : 3

cube of 0 is 0.

cube of 1 is 1.

cube of 2 is 8

#include<iostream>
