This program is calculating and displaying the average of 3 groups of numbers in output file. Data is arranged in file so each group of numbers is preceded by number of data items in each group. It works for 2nd & 3rd group but calculation for 1st group is wrong. Thanks for your help!

```
//numbers.cpp
#include <iostream>
#include <fstream.h>
#include <stdlib.h>
using namespace std;
int main()
{
int numb, tot, count, sum;
float avg;
ifstream innumb;
ofstream outnumb;
innumb.open("innumb.txt");
outnumb.open("outnumb.txt");
if (innumb.fail())
{
cout<<"Output file doesn't exist!";
exit(1);
}
while (!innumb.eof())
{
innumb>>numb;
count = numb;
for (tot=0; tot<count; tot++)
{
innumb>>numb;
sum = sum+ numb;
}
avg = sum/count;
outnumb<<"The average of this group is: "<<avg<<endl;
sum =0;
avg=0;
}
system("PAUSE");
return 0;
}
//This is the run i get:
//The average of this group is: 4.01863e+008
//The average of this group is: 86
//The average of this group is: 75
```
