Reading/Writing text file

HumCH12 (8)
Hi I have this question here,
Write a program that reads data from a text file that contains information about the rainfall amounts during a specific period and reports the total and average rainfall for the specified period. The text file will have the year, start month, and end month of the period in the first three lines of the file and then the rainfalls amounts in that period.

  #include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
using namespace std;


int main()
{
	ifstream myFile;
	ofstream outFile;
	
	myFile.open("AverageRainfall.txt");

	if (myFile && outFile) {
		int year;
		string month;
			
		double rainfall;
		double totalRain = 0.0;

		while (myFile >> year >>  month >> rainfall) {
			totalRain++;
			sum += total;
			cout << "During " << month << "-" << month
				<< year << "\t" << "The total rainfall was: "
				<< totalRain
				<< endl;
			}
		float average = sum / totalRain;
		outFile << "Rain average is: " << average << endl;
		myFile.close();
		
	}
	else {
		cout << "Error in opening the input/output text file" << endl;
	}
	
	system("pause");
    return 0;
}

and when I run this the notepad file doesn't get read and output, the file is with the source files aswell. Any help on where I could take this next?

You will need to have startMonth and endMonth variables ...
