use 2-dimension array of integers that has 6 rows representing the lakes and 4 columns representing the fish

Afarian (10)
OK, so I have to read integers from a file, the integers are
8 27 33 14 81 146 305
249 412 71 226 4 144 55
94 493 133 265 788 240
380 117 88 25 60

I have been able to read from the file and put them in the rows and columns, but I am having some trouble getting the sum and Average of the integers. Here is my code

//This program uses a 2 dimension array to determine the population of 4 fish in 6 Oklahoma lakes

#include <iostream>

using namespace std;

ifstream DataFileIn;

void ComputeSums(int twoarrays[][4], int sum[], double ColSums[]);

//*************************************************************************
int main()

	int row, column;
	int twoarrays[6][4];

	for(row = 0; row < 6; row++)			//Reads the integers from file to rows and columns
		for(column = 0; column < 4; column++)
			DataFileIn>>twoarrays[row][column];

	cout<<setw(14)<<"Fish1"<<setw(6)<<"Fish2"<<setw(6)<<"Fish3"<<setw(6)<<"Fish4"<<setw(6)<<"Sums"<<setw(10)<<"Averages"<<endl<<endl;
	for(row = 0; row < 6; row++)			//Prints the rows and columns from the file to output
	{

		for(column = 0; column < 4; column++)
		{
			cout<<setw(6)<<twoarrays[row][column];
		}
		cout<<endl<<endl;
	}
}

//*************************************************************************
void ComputeSums(int sum[], int twoarrays[][4])
{
	DataFileIn.open("F:\\DataFile3.txt");
	int row, column;

	for(row = 0; row < 6; row++)			//Reads the integers from file to rows and columns

	cout<<setw(14)<<"Fish1"<<setw(6)<<"Fish2"<<setw(6)<<"Fish3"<<setw(6)<<"Fish4"<<setw(6)<<"Sums"<<setw(10)<<"Averages"<<endl<<endl;
	for(row = 0; row < 6; row++)			//Prints the rows and columns from the file to output
	{
		sum=0;
		cout<<"Lake "<<row + 1<<"  ";
		for(column = 0; column < 4; column++)
		{
			cout<<setw(6)<<twoarrays[row][column];
			sum = sum + twoarrays[row][column];
		}
		cout<<setw(6)<<sum<<setw<<endl; //does not output sum to "Sums" column
				cout<<endl<<endl;
	}
}


I have to do the sum and average in seperarte functions and allow the data to pass to and from the function. Any advice/assistance will be appreciated

By the way an array of 6 rows and 4 columns has 24 elements. Your file contains 25 elements.:)

I just noticed that, but unfortunately it's reading from a file our professor gave us, so we can't edit the datafile.
