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

    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;

    int main()
    {
    	int n,i,s;

    }
    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.
