Find the average of 2o students by using a file and array & use 1 dimensional array

[misbah sajid]

is this according to it??
#include <iostream>
#include <fstream>

using namespace std;

int main(void)
{
fstream file("textfile.txt");
int linecount = 0;
int tempArray[100];
int *finalArray;

while (!file.eof())
{
file >> tempArray[linecount];
linecount++;
}

cout << "Number of lines: " << linecount;

finalArray = new int[linecount];
for (int i = 0; i < linecount; i++)
{
finalArray[i] = tempArray[i];
}

// Print the array.
cout << endl << "The array:" << endl;
for (int i = 0; i < linecount; i++)
{
cout << finalArray[i] << endl;
}

// Perform some operation with array content.
int result = finalArray[0] + 3;
cout << "finalArray[0] + 3 = " << result;

delete[] finalArray;
int endP;
cin >> endP;
return 0;
}

I don't see where you calculate the average.

Just loop through the array and add up the 20 elements then divide by 20.
