Question 11. Question : (TCO 4) If the function square(x) returns the square of x, then x should be passed by

value so it is protected (cannot be changed).

reference so it is protected (cannot be changed).

pointer so it is protected (cannot be changed).

None of the above. X cannot be protected; square can change the value of x regardless of how it is passed.

Question 19. Question : (TCO 4) Assume you have a class, called Simple, that has two data members, a and b, both of type int. What can be said about the function prototype given below? (Choose the best answer.) Simple(int=0, int=0);

It is the prototype for the default constructor.

It is the prototype for the 2-argument constructor.

It is both the 0-argument, and the 2-argument, constructor.

It is incorrect.

Question 20. Question : (TCO 4) Which of the following is a valid declaration to overload the following function? int whatever (double x);

Question 21. Question : (TCO 4) What is the default behavior for the overloaded operator and the copy constructor functions?

There is no default behavior. The user has to write both functions.

It is shallow copy.

It is deep copy.

Both functions are empty stubs.

Question 22. Question : (TCO 4) Assume you have to write a class that makes use of dynamic memory allocation (the class needs to allocate and deallocate memory). According to best practices, which function should you overwrite for proper memory management?

Assignment operator function

Copy constructor

Assignment operator and copy constructor

None of the above

Question 23. Question : (TCO 4) Assume you have to write a class that makes use of dynamic memory allocation (the class needs to allocate and de-allocate memory). According to best practices, where would the keyword new be placed?

Classes are smart data types. The compiler takes care of calling new/delete.

In the constructor

In the destructor

In a separate, dedicated function
