Cannot convert int to int[][] - c++

Question

I am doing a a problem using Multi-dimensional Arrays. I call the function in main but I get this Error message. This is the Original Problem I have:
A local zoo wants to keep track of how many pounds of food each of its three tigers eats each day during
a typical week. Write a program that stores this information in a two-dimensional 3 x 7 array, where
each row represents a different tiger and each column represents a different day of the week. The
program should first have the user input the data for each tiger. Then it should create a report that
includes the following information:
Average amount of food eaten by each of the tigers during the week.
Average amount of food eaten by all the tigers per day for each day.
The least amount of food eaten during the week by any tiger.
The greatest amount of food eaten during the week by any tiger.
the code:
#include <iostream>
using namespace std;
const int TIGERS = 3;
const int DAYS = 7;
int food[TIGERS][DAYS];
void inputArray(int food[TIGERS][DAYS]);
float AvgTig(float);
float Least(float);
float most(float);
int main()
{
float maximum;
float minimum;
float total = 0.0f;
float average = 0.0f;
float result = 0;
inputArray(food);
maximum = food[0][0];
minimum = food[0][0];
cout << "\n \n";
AvgTig(result);
cout << "\n \n";
Least(minimum);
cout << "\n \n";
most(maximum);
cout << "\n \n";
system("PAUSE");
return 0;
//end program
}
void inputArray(int food[TIGERS][DAYS])
{
int total = 0;
for (int tig = 0; tig < TIGERS; tig++) {
for (int day = 0; day < DAYS; day++) {
cout << "TIGER " << (day + 1) << ", day " << (day + 1) << ": ";
cin >> food[tig][day];
}
cout << endl;
}
}
float AvgTig(float output)
{
int total = 0;
for (int i = 0; i < TIGERS; i++) {
for (int day = 0; day < DAYS; day++) {
total += food[i][day];
}
cout << endl;
}
output = total / (TIGERS * DAYS);
cout << "Average food for Tigers in the days is :" << output << " ";
return output;
}
float Least(float minimum)
{
for (int least = 0; least < TIGERS; least++) {
for (int day = 0; day < DAYS; day++) {
if (food[least][day] < minimum)
minimum = food[least][day];
}
}
cout << "Minimum food eaten: " << minimum << " ";
return minimum;
}
float most(float maximum)
{
for (int most = 0; most < TIGERS; most++) {
for (int day = 0; day < DAYS; day++) {
if (food[most][day] > maximum)
maximum = food[most][day];
}
}
cout << " Maximum number of food is: " << maximum << " ";
return maximum;
}

On this line:
inputArray(food[TIGERS][DAYS]);
in main, you are calling inputArray with a single int, and not the entire food array. In fact, even reading this position in food is UB.
You need to call the function like this:
inputArray(food);
