Your logic is correct. Just use long int or long long instead of int for n and sum as contraints are till 10^9. It should give AC then.

You might search your doubt on the forum before posting straightaway.

#include
using namespace std;

int main()
{
int N,answer=0;
cin>>N;
for(int i = 1 ; i <= N ; i++)
{
answer = answer + i;
}
cout<<answer;
}

Why isn’t this code running

It was just one comment before that I mentioned the answer. Please try to read earlier threads and comments before posting your code blindly @invincible_a99

Also, Please format your code next time :slight_smile:
