Basic C++ code?

[SMA01]

I'm having trouble getting this code to work:

Given the availability of a file named numbers write the statements necessary to read an integer from standard input and then read in that many values from numbers and display their total.

This is what I put in:

int a;
cin << a;
numbers.open("numbers");
numbers<<a;
cout >>numbers

For starters cin >> a instead of cin << a; also cout << numbers, not cout >> numbers

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
    ifstream fin("numbers.txt"); // file named numbers

    int NumberOfNumbers, sum = 0;
    cin >> NumberOfNumbers;      // integer from standard input

    while(NumberOfNumbers--)     // that many values from numbers
    {
        int read;
        fin >> read;             // reading in
        sum += read;             // tracking total
    }
    cout << sum;                 // display thier total
}

I know I'm not supposed to give answers, but I'm just having a lazy evening.

Oh wow, I can't believe I didn't notice that, my mistake.
