Thread: C++ test questions

I am carrying this over from the C board. I am an instructor who teaches programming. I have many test questions and test banks with questions. However, I was looking for some good test questions that you on the C++ programming board can provide me. I will share you mine If you will share yours.

Thanks. Let's begin

Code:

Which is true?
A.  A derived class may have more than base class.
B.  A base class may have more than one derived class.
C. both (a) and (b)
D.  neither (a) nor (b)

Code:

Select the format for inheriting multiple classes.
A.  class Derived: public class Base1 : public class Base2
B.  class Derived: public class Base1, Base2
C.  class Derived: public Base1, public Base2
D.  class Derived: (public Base1; public Base2;)

Answers will come later- Mr. C.

Yes, C is right in both cases.

Code:

memcmp would return ___________ for the call
memcmp("Hi, how are you?", "Hi, how are things?", 6);
(a) -1
(b) a negative number.
(c) zero.
(d) a positive number.

Code:

What is wrong with the following abstract class definition?
class Shape {
public:
virtual double print() const;
double area() const { return base * height;}
private:
float base;
float height;
}
(a) There are no pure virtual functions.
(b) There is a non-virtual function.
(c) Private variables are being accessed by a public function.
(d) Nothing.

I do other see people points-that's why I am trying to write the questions clearer and less ambigous. That's why I have all these pointer questions laying around.

Mr. C.

This time we are in agreement the answer is C.

Mr. C.

If you're looking for questions you might check out the quiz:
http://www.cprogramming.com/cgi-bin/quiz.cgi

Yes, that quiz on the site is a good place were. I can send my students for a quick review of C++ concepts.

I just want some other questions. I can come up with my own but I like seeing what other people think.
