OOP Lab 16: Matrix Class Dynamic Operators

LIVE← Prev Next →

Problem Objective

Add dynamic operator overloading functions to a 2D Matrix class:

Data Members & Memory:

◦
Private attributes: int rows, int cols, int** data (dynamically allocated 2D integer array).
◦
Parameterized constructor Matrix(int r, int c) allocating memory and initializing elements.
◦
Copy Constructor Matrix(const Matrix& other) performing deep copy.
◦
Destructor ~Matrix() releasing dynamic 2D memory with delete[].

Overloaded Operators:

◦
Assignment (operator=): Deep copy with self-assignment guard (if (this != &other)).
◦
Addition (operator+): Element-wise addition for equal dimensions.
◦
Subtraction (operator-): Element-wise subtraction for equal dimensions.
◦
Multiplication (operator*): Dot product matrix multiplication (r1 x c1) * (c1 x c2) -> (r1 x c2).

Display & Utility:

◦
set(int r, int c, int val) and display() const.

In `main()`:

◦
Instantiate matrices A and B, set values, and demonstrate A + B, A - B, A * B, and assignment C = A.

Expected Terminal OutputStandard Out

Matrix A (2x2):
  [ 1 2 ]
  [ 3 4 ]
Matrix B (2x2):
  [ 5 6 ]
  [ 7 8 ]
Matrix Addition (A + B):
  [ 6 8 ]
  [ 10 12 ]
Matrix Subtraction (A - B):
  [ -4 -4 ]
  [ -4 -4 ]
Matrix Multiplication (A * B):
  [ 19 22 ]
  [ 43 50 ]

[✓] Matrix dynamic operators verified (Time: 0.009s, Memory: 2.2 MB)

Execution Constraints

›Dynamic 2D allocation using new int*[rows] and new int[cols]
›Deep copy in copy constructor and operator=
›Memory leak prevention in ~Matrix()

Implementation Checklist

Define Matrix class with dynamic 2D arrayImplement copy constructor and destructorImplement operator= with self-assignment checkImplement operator+ and operator- for element-wise arithmeticImplement operator* for matrix multiplicationTest matrix operations in main()
