Assignment: Lab 7 Polymorphism
Description: This lab introduces students to the concepts of polymorphism, early binding, late binding, abstract classes, and virtual class functions. This will be done in the context of performing calculations on basic geometrical shapes. Polymorphism is a very powerful extension of inheritance, and by using pointers to the base class, it allows access to derived class objects and their functions based on the context that they are called in.
The lab will require the creation of a base geometric class, called Shape, and two sub classes, Circle and Rectangle, that are derived public from the class Shape. From there, objects of both the Circle and the Rectangle classes will be created, as will an array of pointers to the base class Shape. By using the instantiated objects and the object pointers, both static and dynamic binding will be demonstrated.

Assignment: Lab 6 Overloaded Operators
Description: This lab is to introduce students to the concept of operator overloading as member functions of a class. This will be done in the context of creating a class that will perform four basic mathematical operations on complex numbers.
The C++ compiler has defined operators for all the arithmetic and assignment operations for its native data types, such as integer, float, double, and so forth. However, for user-defined data types, such as classes and structures, these operations are undefined.
C++ allows the programmer to create new definitions for these operators so that they can operate specifically on these user-defined data types. Which set of operators is actually called and implemented is decided during the compilation, and it is based on the data types of the operands involved in the operation.
The ability to define a new set of data-type, dependent operations on existing operators, or functions, is called operator overloading.

Assignment: Lab 5 Pointers and Pointer Operators
Description: This lab will explore the use of pointers in several ways. Pointers will be used to dynamically allocate memory for new class objects on demand from the user, and they will be used to access class-member functions. Pointer arithmetic will be used to access and sort class objects according to criteria explained in the lab.
Pointers are, essentially, address variables, or variables that hold as their value the address of other variables. In terms of memory management, they are very powerful devices, and they more closely and efficiently use the actual internal hardware registers of the microprocessor that the program operates on.
Pointers also have the requirement that the pointer type must be of the same data type as the variable, or the data that it points to or holds the address of. The power of pointers also hints at the potential complexity of their use, which is why this lab is focused almost entirely on several different aspects and uses of pointers. The lab also introduces pointer arrays and pointers to pointers.
The Resistor class created in the Week 2 lab will be used as the class that the pointer operations will be used upon. The lab also requires the use of accessor functions and static data members, which may need to be added to the Resistor class definition and implementation.

This lab requires you to use C++ class composition to implement a single pole-filter design program. The program will allow the user to specify resistor and capacitor values and filter type.
Once all the user parameters are specified, the program will return the cutoff frequency values for the filter. Composition may be thought of as a has-a relationship for objects, as compared to inheritance, which may be described as an is-a relationship for objects.
You are required to use two component classes: one for a resistor object and one for a capacitor object. You are then to define and implement a filter class that will contain one object of each the resistor and the capacitor classes in order to create the filter and its characteristics.
The Resistor class created in the Week 2 iLab may be used both as the class definition for the resistor object and as a template or a guide for the capacitor-class definition. The lab also requires you to implement your program in a multiple-file project and create both cpp and h files for each class defined. In addition, the program will have the capacity to save all filter parameters to a text file and read previously designed filter parameters from a text file.
