Hi, everyone. This is my first post here. I'm not very good with C++ and I have to write a program using 2 dimensional arrays.

My program is a Menu that works with 2 two dimensional arrays. The program has to generate two random matrices and perform arthimetic procedures like addition and subtraction. My program generates the matrices perfectly, but I'm having a lot of trouble writing the function to add the two matrices. I know that in order to add to matrices you have to sum the elements in every row and column and store them into a new matrix, but I can't figure out how to write the actual code for it. Can anyone help? PLEASE! Here is the code I have written so far for the program. The addition part of the code is being written in the last function.

```
//February 7, 2005
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <iomanip>
using namespace std;
const int ROW = 3; //global constant for row
const int COL = 3; //global constant for column
const int LOW = 1; //global const for lower limit
const int UP = 10; //global const for upper limit
void RandomArray(int[][COL],int, int, int, int); //Random array generator function prototype
void Menu(); //Menu function prototype
void PrintArray(int[][COL],int,int); //Print array function prototype
void AddArray(int[][COL],int[][COL],int,int);
int main()
{
srand(time(NULL));
int matrix[ROW][COL]; //Array declaration
int NewMatrix[ROW][COL];
int menuOption;
RandomArray(matrix, ROW, COL, LOW, UP); //Function call
do
{
Menu();
cin >> menuOption;
cout << endl;
switch(menuOption)
{
case 1:
RandomArray(matrix, ROW, COL, LOW, UP);
PrintArray(matrix,ROW,COL);
RandomArray(matrix, ROW, COL, LOW, UP);
PrintArray(matrix,ROW,COL);
AddArray(matrix,NewMatrix,ROW,COL);
PrintArray(matrix,ROW,COL);
break;
case 7:
PrintArray(matrix,ROW,COL);
RandomArray(matrix, ROW, COL, LOW, UP);
PrintArray(matrix,ROW,COL);
break;
default:
cout << "Invalid Option." << endl;
break;
}
}while (menuOption != 0);
return 0;
}
void Menu()
{
cout << endl << "Menu Options: " << endl << endl
<< "1. Add 2 matrices " << endl
<< "2. Subtract 2 matrices " << endl
<< "3. Multiply 2 matrices " << endl
<< "4. Multiply matrix by a constant " << endl
<< "5. Transpose matrix " << endl
<< "6. Matrix trace " << endl
<< "7. Print " << endl
<< "0. EXIT " << endl;
}
void RandomArray(int table[ ][COL], int row, int col, int lowerLimit, int upperLimit)
{
for (int r = 0; r < ROW; r++)
for (int c = 0; c < COL; c++)
table[r][c] = rand()%(upperLimit - lowerLimit + 1) + lowerLimit;
}
void PrintArray(int table[][COL], int row, int col)
{
for (row = 0; row < ROW; row++)
{
for (col = 0; col < COL; col++)
cout << setw(3) << table[row][col];
cout << endl;
}
cout << endl;
}
void AddArrays(int table[][COL], int theMatrix[][COL], int row, int col)
{
for (int r=0; r < row; r++)
for (int c=0; c < col; c++)
theMatrix[r][c]= table[r][c]+ table[r][c];
}
```

By the way, should my AddArray function be a value-returning function?
