Write a program in C++ to print Floyd’s Triangle by using the constructor destructor.

Constructor

The constructor T4Tutorials_Floyds_Triangle() is a member function of the class T4Tutorials_Floyds_Triangle. The constructor T4Tutorials_Floyds_Triangle() has the same name as the name of its class T4Tutorails_Series.

When a new object T4Tutorials_Floyds_Triangle object; of the class T4Tutorials_Floyds_Triangle is executed, the constructor T4Tutorials_Floyds_Triangle() also executed automatically.
The constructor T4Tutorials_Floyds_Triangle() has no data type. Even we can’t use void also.
The constructor T4Tutorials_Floyds_Triangle()can have arguments.
The constructor T4Tutorials_Floyds_Triangle()can be only public.
There is no inheritance of the constructor T4Tutorials_Floyds_Triangle().

Destructor

The destructor ~T4Tutorials_Floyds_Triangle() is a member function of the class T4Tutorials_Floyds_Triangle. Destructor ~T4Tutorials_Floyds_Triangle() has the same name as the name of its class T4Tutorials_Series. The tild sign ∼ is used before the name of the destructor ~T4Tutorials_Floyds_Triangle().

When the object T4Tutorials_Floyds_Triangle object;of the classT4Tutorials_Floyds_Triangle destroyed, then the destructor ~T4Tutorials_Floyds_Triangle()also destroyed automatically.
One class T4Tutorials_Floyds_Triangle can have only one destructor ~T4Tutorials_Floyds_Triangle(). However, one class can have many constructors.
Destructor ~T4Tutorials_Floyds_Triangle()overloading is impossible.
The Destructor ~T4Tutorials_Floyds_Triangle()can’t have any arguments(parameters).
The destructor ~T4Tutorials_Floyds_Triangle()has no data type.

#include<iostream>
using namespace std;
class T4Tutorials_Floyds_Triangle
{
	public:
		int i,j,p,q,n;
		public:
//constructor
			T4Tutorials_Floyds_Triangle()         			{
             	cout<<"Please enter the no of rows";
	            cin>>n;
               	for(i=1;i<=n;i++)
             	{
		if(i%2==0)
		{
			p=1;
			q=0;
		}
		else
		{
			p=0;
			q=1;
		}
		for(j=1;j<=i;j++)
		{
			if(j%2==0)
			{
				cout<<p;
			}
			else
			{
				cout<<q;
			}
		}
		cout<<endl;
	}
}
	~T4Tutorials_Floyds_Triangle()       // destructor
	{
	}
};
int main()
{
	T4Tutorials_Floyds_Triangle object;
	return 0;
}

#include<iostream>

using namespace std;

class T4Tutorials_Floyds_Triangle

{

public:

int i,j,p,q,n;

public:

//constructor

T4Tutorials_Floyds_Triangle() {

cin>>n;

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

{

{

p=1;

q=0;

}

else

{

p=0;

q=1;

}

for(j=1;j<=i;j++)

{

if(j%2==0)

{

cout<<p;

}

else

{

cout<<q;

}

cout<<endl;

}

~T4Tutorials_Floyds_Triangle() // destructor

{

}

};

int main()

{

T4Tutorials_Floyds_Triangle object;

return 0;

}

Output
