Examination 3 Guide*

The exam will be comprehensive, but will focus on topics from D&D Chapters 6-9, 11.

1. Defining class members (data and methods).
2. constructors (default and otherwise) and destructors
3. initial values for constructors
4. referencing structure members (. notation), member selection operator
5. this pointer and the -> operator
6. ~ in destructor name
7. :: scope resolution operator
8. friend functions
9. operator overloading (binary only)
10. Base and derived classes.
11. Public, private and protected member attributes
12. Overriding base class members in a derived class
13. Using dec, oct, hex and setbase qualifiers in I/O.
14. Structures
15. Abstract data type (ADT)
16. Try, throw and catch.
17. const as a class and variable modifier. That is, the principle of least privaledge.
18. Static alsss members.
19. Assert statement.
20. new, new [], delete, delete [].
21. Be able to briefly what a copy constructor does.
22. "is-a" or "is-a-kind-of" and and "has-a" relationships.
23. No multiple inheritance.

From previous chapters know and understand the following constructs:

1. Passing parameters by value and reference
2. Control statements; for, switch, if, if/else, while, do/while
3. Arithmetic and logical operators (+,-,/,*,++,--,+=,-=,%,...,==,!=,...)
4. Declarations of arrays
5. Concepts of precedence and associativity.
6. break and continue statements/
7. functions and function prototypes
8. recursive functions
9. pointers, use of * and &
10. basic character manipulation functions; strcpy, strcat, strcmp.
11. use of const versus #define
12. Scope of variables.
