Write a class named Location for locating a maximal value and its location in a two-dimensional array. The class contains public data fields row, column, and maxValue that store the maximal value and its indices in a two dimensional array with row and column as int type and maxValue as double type. The class also contains a constructor Location(row, column, maxValue) for creating an instance with the specified row, column, and maxValue.

Question

Write the following function that returns the location of the largest element in a two-dimensional array. Assume that the column size is fixed.
```
const int ROW_SIZE = 3;
const int COLUMN_SIZE = 4;
Location locateLargest(const double a[][COLUMN_SIZE]);
```
The return value is an instance of Location.

Write a test program that prompts the user to enter a 3 by 4 two-dimensional array and displays the location of the largest element in the array. Here is a sample run:

```

Enter a 3 by 4 array:
23.5 35 2 10
4.5 3 45 3.5
35 44 5.5 9.6
The location of the largest element is 45 at (1, 2)

```
#include
using namespace std;

class Location
{
public:
Location(int r, int c, double m)
{
row = r;
column = c;
maxValue = m;
}
int row;
int column;
double maxValue;
};

const int ROW_SIZE = 3;
const int COLUMN_SIZE = 4;
Location locateLargest(const double a[][COLUMN_SIZE])
{
int row = 0;
int column = 0;
double maxValue = a[0][0];

for (int i = 0; i < ROW_SIZE; i++)
for (int j = 0; j < COLUMN_SIZE; j++)
if (maxValue < a[i][j])
{
row = i;
column = j;
maxValue = a[i][j];
}

return Location(row, column, maxValue);
}

int main()
{
double p[ROW_SIZE][COLUMN_SIZE];

cout << "Enter a 3 by 4 two-dimensional array:";
for (int i = 0; i < ROW_SIZE; i++)
for (int j = 0; j < COLUMN_SIZE; j++)
cin >> p[i][j];

Location loc = locateLargest(p);

cout << "The location of the largest element is " <<
loc.maxValue << " at (" << loc.row << ", " << loc.column << ")" << endl;

return 0;
}
