But before you can run it, you will need to fix the compile errors - particularly relating to missing ;

int main()
{
int n,i,s;
cout<<"Insert number of n"<<endl;

s=0;

}
If you want to learn C++, you need to understand the syntax of the language. These are simple errors that even a beginner should be able to find and fix easily.
By the way, the answer is 10.
S = (N * (N + 1)) / 2;
Now write a program to find 12 + 22 + 32 + 42.

Re: help me with c++
Code:
#include <iostream.h>
This is not standard ANSI c++. For standard ANSI c++ your headers should be
Code:
#include <iostream>
#include <cstdlib>
using namespace std;
