Thread: classify number-to file not screen

I am trying to make this change to read and write to a file with the file length unknown and to add into the program the sum and average of the number read from the file


Program: Classify Numbers
This program counts the number of zeros, odd, and even numbers *?*/

Code:

#include <iostream>
#include <iomanip>
#include <fstream>

using namespace std;


//Function prototypes
void initialize(int& zeroCount, int& oddCount, int& evenCount);
void getNumber(int& num);
void classifyNumber(int num, int& zeroCount, int& oddCount, int& evenCount);
void printResults(int zeroCount, int oddCount, int evenCount);
bool getNumber(ifstream& numberFile, int& zeros, int& odds, int& evens);
void writeNumber(ofstream& resultsFile, int zeros, int evens, int odds, int sum, int avg);
void calcSum( int zeros, int evens, int odds);

int main ()

    int avg;




    //Variable declaration
    int counter; //loop control variable
    int number; //variable to store the new number
    int zeros; //variable to store the number of zeros
    int odds; //variable to store the number of odd integers s
    int evens; //variable to store the number of even integers
    //int sum; // sum of the numbers
    //int avg; //average of the number

    initialize(zeros, odds, evens); //Step 1

    //cout << "Please enter " << N << " integers."
    // << endl; //Step 2
    //cout << "The numbers you entered are: "
    // << endl;

    //numberfile.open ("f:number.dat");

    // if(inFile)

        }// end for loop

        // calcSum (zeroCount, evenCount, oddCount);
        writeNumber(resultsFile, zeros, odds, evens, sum, avg);
    }


    cout << endl;

    return 0;
