Sum of the series Using Destructor in C++

Sum of the series Using Destructor in C++.

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

When the object obj(5) of the class T4Tutorials_Series destroyed, then the destructor ~T4Tutorials_Series() also destroyed automatically.
One class T4Tutorials_Series can have only one destructor ~T4Tutorials_Series(). However, one class can have many constructors.
Destructor ~T4Tutorials_Series() overloading is impossible.
The Destructor ~T4Tutorials_Series() can’t have any arguments(parameters).
The destructor ~T4Tutorials_Series() has no data type.

#include <iostream>
using namespace std;
class T4Tutorials_Series
{
	public:
		T4Tutorials_Series (int number)
		{
			int k=9;
			int sum=0;
				cout<<"input the number of terms";
				cin>>number;
				for(int i=1;i<=number;i++)
				{
					sum=sum+k;
					k=k*10+9;
				}
				cout<<"sum os T4Tutorials_Series"<<sum;
		}
	~T4Tutorials_Series()
		{
			cout<<"construction complete its work, FREE MEMORY"<<endl;
		}
	};
		int main()
		{
			T4Tutorials_Series obj(5);
		}

#include <iostream>

using namespace std;

class T4Tutorials_Series

{

public:

T4Tutorials_Series (int number)

{

int k=9;

int sum=0;

cout<<"input the number of terms";

cin>>number;

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

{

sum=sum+k;

k=k*10+9;

}

cout<<"sum os T4Tutorials_Series"<<sum;

}

~T4Tutorials_Series()

{

cout<<"construction complete its work, FREE MEMORY"<<endl;

}

};

int main()

{

T4Tutorials_Series obj(5);

}

Output

Please input the number of terms. 5

The sum of T4Tutorails_ Series is 111105.
