Write a program to add even numbers  up to nh  by using for loop in c++ language. 

#include<iostream>

using namespace std;

int main()
{ 
      int i , n, sum =0;

      cout<<"Add even numbers  up to nth term  "<<endl;

      cout<<"Enter the number of term (nth) = ";
      cin>>n;
     
     for(i=2;i<=n;i=i+2 )//  intialization i=2;
                     // upgradation ,increment by 2

     {  sum =sum + i ;  }

     cout<<"sum of "<<n<<"th term of only even number = "<<sum;
 return 0;
}

• OUTPUT

Add even numbers  up to nth term  

Enter the number of term (nth) = 15

the sum of 15th term of only even number = 56
