Is the above program correct?
What is your program all about?
Write a C++ program to multiply two order matrices
What does 'order matrix' mean?
What is your original assignment?
Original assignment: Write a C++ program to multiply any two order matrix with pointers.
Order of matrix: Number of rows and columns in it.
Two order matrix : has two rows and two columns.
