Help finding the average of reach row in a 2D array function

[CodecSmash49]

im currently working on a assignment, where you have 3 monkeys that are feed for 7 days. You have to use a 2D array to gather the info. display like a chart, and find the average eaten each day.

This is the code I have so far. I only need help with displaying it as a chart and finding the average. Please ^.^

 
#include <cstdlib>
#include <iostream>
 
using namespace std;
 
void getFood(double arrayPound[3][7]);
void displayFood(double arrayPound[3][7]);
void sortLeast(double arrayPound[3][7]);
void sortGreatest(double arrayPound[3][7]);
void sortAverage(double arrayPound[3][7]);
 
int main(int argc, char *argv[])
{
double arrayPound[3][7];
 
getFood(arrayPound);
cout << endl;
 
displayFood(arrayPound);
cout << endl;
 
sortAverage(arrayPound)
cout << endl;
 
sortLeast(arrayPound);
sortGreatest(arrayPound);
 
 
 
system("PAUSE");
return EXIT_SUCCESS;
}
 
void getFood(double arrayPound[3][7])
{
double pound = 0;
 
cout << "Food for the monkeys." << endl;
cout << endl;
 
for(int i = 1; i < 4; i++)
{
for(int u = 1; u < 8; u++)
{
cout << "Please enter the amount feed to monkey " << i << " on day " << u << " :";
cin >> pound;
 
while((cin == 0) || (pound < 0))
{
cin.clear();
cin.ignore(10000, '\n');
cout << "Please enter the amount feed to the monkey: ";
cin >> pound;
}
arrayPound[i][u] = pound;
}
}
 
}
 
void displayFood(double arrayPound[3][7])
{
double pound;
 
cout << "Total food eaten across all 7 days." << endl;
cout << endl;
 
for(int i = 1; i < 4; i++)
{
for(int u = 1; u < 8; u++)
{
cout << "The amount eaten by monkey " << i << " on day number " << u << " was: " << arrayPound[i][u] << endl;
}
}
}
 
void sortLeast(double arrayPound[3][7])
{
double leastVal = arrayPound[0][0];
 
for(int i = 1; i < 4; i++)
{
for(int u = 1; u < 8; u++)
{
if(arrayPound[i][u] < leastVal)
{
leastVal = arrayPound[i][u];
}
}
 
}
cout << "The least amount was eaten: " << leastVal << endl;
}
 
void sortGreatest(double arrayPound[3][7])
{
double greatestVal = arrayPound[0][0];
 
for(int i = 1; i < 4; i++)
{
for(int u = 1; u < 8; u++)
{
if(arrayPound[i][u] > greatestVal)
{
greatestVal = arrayPound[i][u];
}
}
}
cout << "The greatest amount was eaten: " << greatestVal << endl;
}
 
void sortAverage(double arrayPound[3][7])
{
double dailyAvg;
 
for(int u = 1; u < 8; u++)
{
( arrayPound[1][u] + arrayPound[2][u] + arrayPound[3][u] ) / 3 = dailyAvg;
}
 
cout << "The average eaten by the monkeys on day " << u << " was: " << dailyAvg << endl;
 
}

What kind of chart are you to display?

I haven't analysed your code to get some sense of the underlying algarithm (please use code tags) but I question the need for 5 2d arrays as an over complication. Have you given any thought to using just one array splitting monkeys and days and performing the required data manipulation by successive traverses?
