Hi, my assignment asked me to make a 3 row, 7 column array that asked the user to input amount of food for 3 monkeys. 7 represents the number of days. It should tell the user the average, highest and lowest amount for this..

Here is what I've got so far... but it seems to crash when I run it... Can anyone help me identify the problem?

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

//Global Variable
const int COLS = 7;
//Function prototypes
double getAverage (double pounds[][COLS], int rows);
double getHighest(double pounds[][COLS], int rows);
double getLowest (double pounds[][COLS], int rows);

int main()
{
const int NO_MONKEY = 3;
const int NO_DAYS = 7;
char day[7][11] = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
double food[NO_MONKEY][NO_DAYS], average, lowest, highest;

//Input amount of food
for(int monkey = 0; monkey < NO_MONKEY; monkey++)
{
cout << "Enter pounds of food for Monkey " << monkey + 1 << ": \n";
for(int i = 0; i < NO_DAYS; i++)
{
cout << setw(11) << left << day[i] << ": ";
cin >> food[monkey][i];

//Input validation
while(food[monkey][i] < 0)
{
cout << "Invalid Entry! Do not enter negative value for amount of food!\n\a";
cout << setw(11) << left << day[i] << ": ";
cin >> food[monkey][i];
}
}
cout << endl;
}

//Call functions
highest = getHighest(food, NO_MONKEY);
average = getAverage(food, NO_MONKEY);
lowest = getLowest(food, NO_MONKEY);

//Display report
cout << "This is the report: \n";
cout << "Least amount of food eaten by any monkey           : " << lowest << " pounds\n";
cout << "Greatest amount of food eaten by any monkey        : " << highest << " pounds\n";
cout << "Average amount of food eaten per day by all monkeys: " << average << " pounds\n";

return 0;
}

double getHighest(double pounds[][COLS], int rows)
{
double highest;

//Initialization for lowest
highest = pounds[0][0];

//Check other values for lowest
for(int i = 0; i < rows; i++)
{
for(int z = 0 ; z < COLS; i++)
pounds[i][z] > highest? highest = pounds[i][z]: highest = highest;
}

return highest;
}

double getAverage(double pounds[][COLS], int rows)
{
double averageFood, total = 0;

for(int i = 0; i < rows; i++)
{
for(int z = 0 ; z < COLS; i++)
total += pounds[i][z];
}

//Calculate average
averageFood = total / 7.0;

return averageFood;
}

double getLowest(double pounds[][COLS], int rows)
{
double lowest;

//Initialization for lowest
lowest = pounds[0][0];

//Check other values for lowest
for(int i = 0; i < rows; i++)
{
for(int z = 0 ; z < COLS; i++)
pounds[i][z] < lowest? lowest = pounds[i][z]: lowest = lowest;
}

return lowest;
}``````

Oh. I was careless...
Thanks :)
