Virtual base class C++ Program to pattern like a pyramid repeat the number

Write a program in C++ to make such a pattern like a pyramid with a number which will repeat the number in the same row by using the virtual base class in Object Oriented Programming.

#include<iostream>
using namespace std;
class A
{
	public:
		int n;
		public:
			A()
			{
				n=5;
			}
};
class B:public virtual A
{
	public:
		int r;
};
class C:virtual public A
{
	public:
		int sp;
};
class D:public B,C
{
	int disp;
	public:
		void T4Tutorials_Display()
		{
			for(r=1;r<=n;r++)
			{
				for(sp=1;sp<=n;sp++)
				{
					cout<<" ";
			}
			n--;
			for(disp=1;disp<=r;disp++)
			{
				cout<<" "<<r;
			}
			cout<<endl;
		}
	}
};
int main()
{
	D obj;
	obj.T4Tutorials_Display();
}

#include<iostream>

using namespace std;

class A

{

public:

int n;

public:

A()

{

n=5;

}

};

class B:public virtual A

{

public:

int r;

};

class C:virtual public A

{

public:

int sp;

};

class D:public B,C

{

int disp;

public:

void T4Tutorials_Display()

{

for(r=1;r<=n;r++)

{

for(sp=1;sp<=n;sp++)

{

cout<<" ";

}

n--;

for(disp=1;disp<=r;disp++)

{

cout<<" "<<r;

}

cout<<endl;

}

};

int main()

{

D obj;

obj.T4Tutorials_Display();

}

Output

Print pyramid pattern using do while loop c++

Develop a C++ Program to print the pattern like a pyramid repeating the number by using the Virtual base class in OOP. Develop a C++ Program to print the pattern like a pyramid repeating the number by using multi level inheritance and virtual base class. Develop a C++ Program to print the pattern like a pyramid repeating the number by using the Virtual base class with for loop.
