True

Question 3

C++ does not allow the use of pointers for indirect addressing.

Answer 3

False

Question 4

C++ allows the use of references for indirect addressing.

Question 5

C++ uses object-oriented program design.

Question 6

C uses procedural program design.

Question 7

C was created from C++.

Question 8

C++ is sometimes referred to as "a better C".

Question 9

Many introductory C++ courses are taught using procedural programs initially.

Question 10

/* this is a comment */ is not a valid C++ comment.

Question 11

Any text after the \\ delimiter, but only to the end of the current line, is taken to be a comment in C++.

Question 12

The header files in C++ are different from those in C, but perform the same task and occupy similar positions in a C++ program that they occupy in a C program.

Question 13

C++'s cin does not require the address operator needed for C's scanf() function.

Question 14

C++ uses newl to signify a new line.

Question 15

One of the driving forces in the creation of object-oriented languages was the inability of procedurally structured code to be extended easily without extensive revisions, retesting, and reevaluations.

Question 16

Object-oriented languages make it easier to reuse code in a manner that significantly increases software productivity.

Question 17

A data type provides both a set of values and a set of operations that can be applied to these values.

Question 18

A programmer-defined data type is known as an ADT.

Question 19

In a class, values defined for the data type can only be accessed and operated on by functions specified as part of the class.

Question 20

Polymorphism permits existing code, which has been thoroughly tested, to be reused efficiently without the need for extensive retesting.

Question 21

A parent class is also called a derived class.

Question 22

A derived class is also called a child class.

Question 23

Using polymorphism, existing operations on a base class can be left alone, without the need to retest and reverify them, while they are extended to a derived class.

Question 24

C++ is a true object-oriented language.

Question 25

In a true object-oriented language all programs would have to adhere to an object-oriented structure.
