#include <iostream>
using namespace std;
int main()
{
int n,i,sum=0;
cout << "
Display n terms of natural number and their sum:
";
cout << "---------------------------------------
";
cout << " Input a number of terms: ";
cin>> n;
cout << " The natural numbers upto "<<n<<"th terms are:
";
for (i = 1; i <= n; i++)
{
cout << i << " ";
sum=sum+i;
}
cout << "
The sum of the natural numbers is: "<<sum << endl;
