This is my first post here and I am in need with some help(might need a lot) with a lesson my professor has given me to help me understand loops.

Here is an imgur link to my current homework. http://i.imgur.com/9Mcja.jpg

As you can see on there I have them listed on which ones are supposed to be sentinel and which ones are supposed to be count control loops.

This is currently what I have:

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

void main()
	int count = 0;
	int sum = 0;
	int num;

	ofstream fileout;
	ifstream filein;

	filein.open("C:\\Users\\commiedic\\Desktop\\New folder\\datafile2.txt");
	fileout.open("C:\\Users\\commiedic\\Desktop\\New folder\\answers.txt");

	{ sum=sum+num;}

This class has me stumped currently and I am having a hard time breezing through the class at my instructors speed. So I don't want to get too far behind.

Right now this program is giving me an error that opens CMD and gives me infinite lines of "0's".
