You should be able to define or explain the following terms:
- data structure
- major differences between C++ and Python
- scope of a variable
- pass by value (a.k.a. copy by value), pass by pointer (e.g., arrays)
- object oriented programming and its major properties (e.g., abstraction,
modularity, reusability, encapsulation)
- instance of a class (i.e., object)
- function call stack
- the heap
- inheritance, is-a relationship
- base class, derived class (a.k.a., parent class, child class)
- pseudocode (both interpreting and writing)
You should be familiar with all aspects of basic C++ programs,
such as those you created for labs 01 and 02. This includes:
- how to compile and execute C++ programs
- the int, float, char, bool, string data types
- variables, assignment with =, and basic arithmetic
- boolean and relational operators in C++
- if / else if / else statements,
while loops, and for loops
- uses of break and continue
- variables, including their declaration, definition, and use
- functions, including their declaration, definition, and use
- arrays (statically allocated)
- basic uses of cout and cin
- basic uses of file streams (i.e., ifstream ofstream)
- purpose of #include and using namespace std;
- void and its use
- pointers, dereferencing, NULL
- dynamic memory management with new and delete
(not for arrays)
- classes, including their declaration and implementation as well as the
use of access control: public, private, and
protected, data members, functions, constructors, destructors
- C++ inheritance
- virtual, pure virtual functions, and abstract classes
- dot notation and arrow notation
- tracing a program using a memory diagram (heap and stack)
- Write a C++ program that prompts the user for an integer n
and then prints a single output integer, the sum of the integers from 1
- Write a boolean function isPrimaryColor that takes a string as an
argument and returns true if the string is "red", "yellow", or "blue", and
returns false otherwise. Then write a program that prompts
the user for a color and uses isPrimaryColor to determine if
their color is primary.
- Draw a memory diagram for
examples:week-03/inheritance/testPerson.cpp as it executes.
Include the stack and the heap.
- Write a Shape class with the following features:
Then write a Rectangle subclass of Shape with the following
- private color (a string) data member.
- a constructor which takes in a color and initializes
the color of the Shape.
- appropriate public getColor(), setColor()
and print() accessor functions. print() should
output the color of the object, e.g. "Shape with color black."
Finally, write a main() function that declares a pointer p
to a Shape, creates a single Rectangle on the heap and saves the pointer to that Shape as p, and then prints the
Shape and releases its memory.
- a private length and width (both int) data members
- a constructor which takes a color, length, and width, which
it uses to initialize the data members.
- accessor functions: getArea() and print(). print should output the area and color of the Rectangle, e.g. "Rectangle with area 20. Shape with color black."
