Write a program in C++ which takes two 4 x 4 matrices as input from the user and displays
the matrices in tabular form. Then ask user to make a choice:
1. Press 1 for matrix addition
2. Press 2 for matrix subtraction
3. Press 3 for matrix multiplication
4. Press 4 for matrix transpose
Use 2D arrays to save matrix values and use functions to perform addition, subtraction,
multiplication and transpose. Refer below examples to understand the concept of matrix
operations.
