| 1. Why would you use: public/private/protected inheritance? |
| 2. Why does the language not define static virtual functions |
|
|
| 3. Can you make a destructor virtual? |
| 4. Why would you want a virtual destructor? |
| 5. How would you print the first 10 characters of a string? |
| 6. When would you use private inheritance? |
| 7. How and why would you implement a '<<' operator for a String class? |
|
|
| 8. When would you use a reference? |
| 9. Why do you want to have virtual member functions? How was "it" done before vmf's came into existence? What was wrong with it? |
| 10. Why is protected" as bad as ""public""?" |
| 11. Give one example use of a static member. |
| 12. Why did new (a new expression) have to be a language-level construct while malloc could be a library function? |
|
|
| 13. What are the advantages and disadvantages of templates over plain old inheritance and heterogenous containers? |
| 14. What are the problems with a tree-style hierarchy? |
| 15. Why is iostream better than stdio? (There are umpteen reasons, I'm just talking about the type-safe answer...) |
| 16. Why would someone want to have RTTI when there are virtual functions? Doesn't that sound contradicting in purpose? Discuss one situation where RTTI could be useful, if you think so. |
| 17. Aren't templates glorified macros? |
| 18. If you know exceptions, aren't you worried that they could turn out to be the modern "goto"? Why isn't it that bad in C++? |
| 19. I would settle for "Why use const instead of #define?" as a question. |
| 20. What's the difference between a declaration and a definition? |
| 21. What's the difference between a struct and a class? |
| 22. Describe for me in 100 words or less how to simulate a virtual table using C. |
| 23. What is the difference between delete[] and delete? |
| 24. I need to write Wombat objects to an ostream. Describe two ways to accomplish this and one way that won't work. |
| 25. What's an initializer list? |
26. Can you think of a 5 letter word to describe the following?
class {
int n;
public:
void setN(int);
int getN() const;
};
(One possible answer: "struct"...) |
| 27. describe how you extend stdio to access streams that the original implementation never heard of (socket stream, etc.). |
| 28. describe how you extend printf to support a new (user defined) type. |
