first program I ever wrote professionally

sms_loadfile.cpp

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

int main()
{
 ifstream input_file_counter("input_file.txt");
 
 int  temp;
 int NUMBER_OF_DOCUMENTS = 0;
 while ( input_file_counter >> temp )
 {
         NUMBER_OF_DOCUMENTS++;
 }
 
 ifstream input_file("input_file.txt");
 ofstream output_file;
 output_file.open("output_file.txt");
 
 int * document;
 document = new int [NUMBER_OF_DOCUMENTS];
 int i, x;
 for(i = 0; i < NUMBER_OF_DOCUMENTS; i++)
 {
   input_file >> document[i];
   output_file << ",Y,,," << document[i] << endl;
 
   for(x = 1; x < document[i]; x++)
     output_file << ",,,," << endl;
 }

 output_file.close();
 input_file.close();
 
 delete [] document;

 return 0;
}
