Write a friend function multElements that takes two Matrix input parameters, checks to see if they are the same size (if not, displays a message stating this) and fills a Matrix output parameter with the products of corresponding elements of the two input parameters.

const int MAX_ROWS = 10;

	const int MAX_COLS = 10;



class Matrix {

public:

Matrix()  {}

private:	

int rows;

int cols;

int mat[MAX_ROWS][MAX_COLS];

};

---

// #4

void multElements( Matrix& result, const Matrix& m1, const Matrix& m2 )

{

   if (m1.rows == m2.rows  &&  m1.cols == m2.cols)

      for  (int i = 0;  i < m1.rows;  ++i)

         for  (int j = 0;  j < m1.cols;  ++j)

            result.mat[i][j] = m1.mat[i][j] * m2.mat[i][j];

   else

      cout << "Error in multElements: Matrix dimensions do not match."

         << endl;

}
