## Help! problem with arrays

A local zoo wants to keep track of how many pounds of food each of its three monkeys eats
each day during a typical week. Write a program that stores this information in a twodimensional
3 × 7 array, where each row represents a different monkey and each column
represents a different day of the week. The program should first have the user input the data
for each monkey. Then it should create a report that includes the following information:
• Average amount of food eaten per day by the whole family of monkeys.
• The least amount of food eaten during the week by any one monkey.
• The greatest amount of food eaten during the week by any one monkey.
Input Validation: Do not accept negative numbers for pounds of food eaten.

This part is the one that I don't understand: • The greatest amount of food eaten during the week by any one monkey.

This is so far what I have:

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

int main()
{
double totalAverage =0;
int monkey, day;

const int NUM_MONKEYS = 3;
const int NUM_DAYS = 7;
double average [NUM_MONKEYS][NUM_DAYS];
double highest, lowest;

cout << "Enter the amount of food in pounds eaten by the referred monkey.\n";

for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
for (day = 0; day < NUM_DAYS; day++)
{
cout << "Monkey " << (monkey + 1) << ", "
<< "Day " << (day + 1) << ": ";
cin >> average [monkey][day];
while ((average [monkey][day] < 0))
{
cout << "Please enter positive values.\n";
cin >> average [monkey][day];
}
}
cout << endl;
}

for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
for (day =0; day< NUM_DAYS; day++)

totalAverage += average [monkey][day]/ NUM_DAYS; // I don't get this part on how to get the average per day for each monkey.
}
//
for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
for (day =0; day< NUM_DAYS; day++)
{
if ((average [monkey][day]) > highest)
highest = average [monkey][day];
}
//
}
for (monkey = 0; monkey < NUM_MONKEYS; monkey++)
{
for (day =0; day< NUM_DAYS; day++)
{
if ((average [monkey][day]) ) LOWEST Y PUES NOSE :S
lowest = average [monkey][day];
}
//
}
cout << fixed << showpoint << setprecision (2); DOUBLE
cout << "The average amount is: " << totalAverage << endl;
cout << "The highest amount is: " << highest << endl;
cout << "The lowest amount is: " << lowest << endl;

system ("PAUSE");
return 0;
}
