Do the matrix operations (add, sub, multiplication) discussed in the class on Tuesday, October 1.

The class Matrix should have the following members, constructor, destructors, and functions:

class Matrix
{
private:
  int rowSize;
  int colSize;
  int ** ptr;
 public:
 Matrix(int rowSize, int colSize);
~Matrix();
void add (const Matrix &second, Matrix &result) const;
void subtract (const Matrix &second, Matrix &result) const;
void multiply (const Matrix &second, Matrix &result) const;
void input( ) const;//input the matrix from the keyboard
void print() const; //display matrix to the console window
};

Write a function to test all the public constructor and methods in the main.

Input two matrices:

Matrix 1

3  2  3  1               
4  4  5  1
4  4  1  5

Matrix 2

4  3  1  3               
3  5  1  5
4  5  1 4

Matrix 3

4  1
5  5
3  4
2  1

Use matrix 1 and matrix 2 for addition and subtraction
Use matrix 1 and matrix 3 for multiplication
