C++ - Practical Two

Vectors and Matrices

---

Write two classes to implement dynamic vectors and matrices in C++.

Both classes must allocate memory dynamically to allow for variable-sized data structures. Use the malloc/free procedures for this purpose. Make this allocation/deallocation in the constructor/destructor.

The following procedures must be implemented in both classes:

• Assign - initialize the data structure with a set of values
• Print - output the data structure
• Add - add another data structure to the current one (overload for both types)
• Multiply - multiply data structure to the current one (overload for both types)

Test your classes thoroughly using all combinations of test data. Also, check for validity of vector/matrix combinations.

Do not implement a user interface. Instead, hard-wire the procedure calls into the main program body.
