Sum of n number of odd natural number using constructor and destructor in C++

Let’s see the Sum of n number of an odd natural number using constructor and destructor in C++.

Constructor

The constructor T4Tutorials_Sum() is a member function of the class T4Tutorials_Sum. The constructor T4Tutorials_Sum() has the same name as the name of its class T4Tutorials_Sum.

When a new object uof the class T4Tutorails_Series is executed, the constructor T4Tutorials_Sum()also executed automatically.
The constructor T4Tutorials_Sum()has no data type. Even we can’t use void also.
The constructor T4Tutorials_Sum() can have arguments.
The constructor T4Tutorials_Sum() can be only public.
There is no inheritance of the constructor T4Tutorials_Sum().

Destructor

The destructor ~T4Tutorials_Sum() is a member function of the class T4Tutorials_Sum. Destructor ~T4Tutorials_Sum() has the same name as the name of its class T4Tutorials_Sum. The tild sign ∼ is used before the name of the destructor ~T4Tutorials_Sum().

When the object obj(5)of the class T4Tutorials_Sumdestroyed, then the destructor ~T4Tutorials_Sum() also destroyed automatically.
One class T4Tutorials_Sum can have only one destructor ~T4Tutorials_Sum(). However, one class can have many constructors.
Destructor ~T4Tutorials_Sum()overloading is impossible.
The Destructor ~T4Tutorials_Sum()can’t have any arguments(parameters).
The destructor ~T4Tutorials_Sum() has no data type.

#include<iostream>
using namespace std;
class T4Tutorials_Sum
{
	public :
	T4Tutorials_Sum();
	~T4Tutorials_Sum();
	void read();
};
T4Tutorials_Sum::T4Tutorials_Sum()
{
	cout<<endl;
}
void T4Tutorials_Sum::read()
{

	{
	
			int n,s=0;
			cout<<"Please enter the value to print odd numbers."<<endl;
			cin>>n;
			for(int i=1;i<=n;i++)
			{
				cout<<2*i-1<<" ";
				s=s+(2*i-1);
				cout<<endl;
			}
			cout<<"T4Tutorials_Sum of given input  = "<<s;
		}
	
}
	T4Tutorials_Sum::~T4Tutorials_Sum()
		{
			cout<<endl<<"The destructor destroys everything of the constructor.";
		}
int main()
{
	T4Tutorials_Sum u;
	u.read();

}

#include<iostream>

using namespace std;

class T4Tutorials_Sum

{

public :

T4Tutorials_Sum();

~T4Tutorials_Sum();

void read();

};

T4Tutorials_Sum::T4Tutorials_Sum()

{

cout<<endl;

}

void T4Tutorials_Sum::read()

{

int n,s=0;

cout<<"Please enter the value to print odd numbers."<<endl;

cin>>n;

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

{

cout<<2*i-1<<" ";

s=s+(2*i-1);

cout<<endl;

}

cout<<"T4Tutorials_Sum of given input = "<<s;

}

T4Tutorials_Sum::~T4Tutorials_Sum()

{

cout<<endl<<"The destructor destroys everything of the constructor.";

}

int main()

{

T4Tutorials_Sum u;

u.read();

}

Output

Please enter the value to print odd numbers.

T4Tutorials_Sum of given input = 25

The destructor destroys everything of the constructor.
