Write a constructor that initializes the matrix dimensions and sets all elements to initVal.

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];
};

Necessary modifications to class definition are underlined



lass Matrix {

public:

	Matrix()  {}

   	Matrix( int, int, int );

private:

	int rows;

	int cols;

	int mat[MAX_ROWS][MAX_COLS];

friend void multElements( Matrix&, const Matrix&, const Matrix&);

};



// #3

Matrix::Matrix( int r, int c, int initVal )

{

   rows = r;

   cols = c;

   for  (int i = 0;  i < r;  ++i)

      for  (int j = 0;  j < c;  ++j)

         mat[i][j] = initVal;

}
