```/****************************************************
Write a program that reads in the file numbers.txt
and prints out the average of the numbers there - for
the moment let's force ourselves to do the average
computation *after* we've read in the whole file.
The file numbers .txt looks like this:

N = 3
DATA:
67
61
82

I.e. there's a header that tells you how many numbers
are in the file, and then you get all the numbers.
****************************************************/
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
// Open input file, read header, get N = # of int's
ifstream IN("numbers.txt");
char c;
int N;
string s;
IN >> c >> c >> N >> s;

// Create array A and read N int's from input
int *A = new int[N];
for(int i = 0; i < N; i++)
IN >> A[i];

// Cycle through array summing all the elements
int sum = 0;
for(int j = 0; j < N; j++)
sum = sum + A[j];

// Print out the average
cout << "The average of the values is "
<< double(sum)/N << endl;

return 0;
}
