Problem 8: A square matrix can be represented by a two-dimensional array with N rows and N columns. You may assume a maximum size of 50 rows and columns.

1. Write the specification for an ADT SquareMatrix. Include the following operations: - MakeEmpty(n), which sets the first n rows and columns to zero. - StoreValue(i, j, value), which stores value into the [i,j] position. - Add, which adds two matrices together. - Subtract, which subtracts one Matrix from another. - Copy, which copies one matrix into another. 2. Convert your specification to a C++ class declaration. 3. Implement the member functions. 4. Write a test plan for your class.
