Which statement is false?
a) A recursive function is a function that calls itself either directly or indirectly through
another function.
b) A recursive function knows how to solve only one or more base cases.
c) The recursion step executes after the original call to the function terminates.
d) In order for the recursion to eventually terminate, each time the function calls itself
with a slightly simpler version of the original problem, this sequence of smaller and

Q1: Problems using switch logic to deal with many objects of different types do not
include:

c. Having to track down every switch statement to do an update of object types.
d. Not being able to implement separate functions on different objects.
Q1: Returning references to non-const, private data:
a. Allows private functions to be modified.
b. Is only dangerous if the binary scope resolution operator (::) is used in the function
prototype.
c. Allows private member variables to be modified, thus "breaking encapsulation."
d. Results in a compiler error.
Which is not a motivation for "functionalizing" a program?
a) The divide-and-conquer approach makes program development more manageable.

a. They both have the same name aside from the tilde (~) character.
b. They are both usually called once per object created.
c. They both are able to have default arguments.
d. Both are called automatically, even if they are not explicitly defined in the class.
The #undef preprocessor directive
(a) can only be used once per macro name.
(b) can only be used on symbolic constants.
(c) allows macros to be redefined with #define later in the program.

Q1: The inline keyword:
a. Increases function-call overhead.
b. Can reduce a function's execution time but increase program size.
c. Can decrease program size but increase the function's execution time.
d. Should be used with all frequently used functions.
Functions are __________ by a function call.

b) invoked
c) internalized
d) inverted
Which is not always required by counter-controlled iteration?
a) The name of a control variable (or loop counter).
b) The initial value of the control variable.
c) The decrement by which the control variable is modified each time through the loop.

looping should continue.
Q1: The putback member function returns to the input stream the previous character
obtained by:
a. A get from the input stream.
b. Using the stream extraction operator on the input stream.
c. Reading input from the keyboard.
d. Reading a file from disk.
The statement
y = &yPtr;

b) assigns the address of the variable yPtr to pointer variable y.
c) is a compilation error.

Q7[C++11]: To prevent class objects from being copied or assigned, you can:
a. Declare as private the class's copy constructor and overloaded assignment operator.
b. Declare the class's copy constructor and overloaded assignment operator with with =
delete after the parameter list.
c. Simply do not declare a copy constructor or assignment operator in the class.
d. (a) or (b).
. Which statement is false?
a) assert is a useful debugging tool for testing if a variable has a correct value
b) If NDEBUG is defined, only the next assertion is ignored.
c) The assert macro is defined in the assert.h header file.
d) One problem with using assert is that if the assertion is false, program execution is
terminated; in some situations it is more appropriate to allow the program to continue
executing after the program has dealt with the problem.
