C++ Program to find the sum of the series using constructor destructor

Write a program in C++ to find the sum of the series using constructor destructor.

#include<iostream>
using namespace std;
class T4Tutorials
{
	public :
	T4Tutorials();
	~T4Tutorials();
	void read();
};
T4Tutorials::T4Tutorials()

{

	{
		cout<<"enter the value";
	int n;
		cin>>n;
  int s=0;
	 int t=1,i=1;
	 for(i=1;i<=n;i++)
  {
  	cout<<" "<<t<<" ";
      if (i<n)
      {
      	cout<<"+";    
      }
     s=s+t;
     t=(t*10)+1;
  }
  cout<<endl<<"The sum is :"<<s;
}
}
	T4Tutorials::~T4Tutorials()
		{
			cout<<endl<<"detail is clear";
		}
int main()
