How to pass two-dimensional array as an argument?

Question

My Matrx class is defined as

class Matrx
{
 double A[50][50];
 int m,n;
public:
 Matrx(void);
 Matrx(int a, int b)
 {
  m=a;
  n=b;
 }
 Matrx o

Thanks to all of you people...you were really helping...I have found myself a new definition of the class and the function definition for the matrix that fitted my need. I need you r comment on it...Below is the example of the class declaration..

#include
#include"stdafx.h"
using namespace std;  
const int M=100; const int N=100;  
class Matrix  
{  
    double A[M][N];  
    int m,n;  
public:  
    Matrix(void);  
    Matrix(int a, int b)  
    {  
        m=a;  
        n=b;  
        for(int i=0;i

and then the function implementation

#include "stdafx.h"
#include "Matrix.h"

Matrix::Matrix(void)  
{  
}  

Matrix Matrix::operator *(Matrix b)  
{  
 Matrix c(m,m);  
 if(n!=b.m)  
 {  
    HWND hndOwner(0);   
    MessageBoxW(hndOwner,L"Multiplication not possible row and column does not match",L"Error",NULL);  
    Matrix errMat(1,0);  
    double er[1][1]={0}; errMat.readMatrix((double *)er);  
    return errMat;  
 }  
for(int i=0;i< m;i++)  
{  
for(int k=0;k< m;k++)  
{  
c.A[i][k]=0;  
for(int j=0;j< n;j++)  
{  
c.A[i][k] = c.A[i][k]+(A[i][j] * b.A[j][k]) ;  
}  
}  
}  
return c;  
}  
Matrix Matrix::operator +(Matrix b)  
{  
    Matrix c(m,n);  
    if((n!=b.n)||(m!=b.m))  
 {  
    HWND hndOwner(0);   
    MessageBoxW(hndOwner,L"Addition not possible row and column does not match",L"Error",NULL);  
    Matrix errMat(1,0);  
    double er[1][1]={0}; errMat.readMatrix((double *)er);  
    return errMat;  
 }  
    for(int i=0;i

The simple codes in the above are working well till now...if you have any suggestion for the improvement please suggest..
