UNIT 5

Question 1

C++ is considered an efficient language for programming games because it is faster to write than other scripting languages. (T/F)

Answer 1

False, C++ is not a scripting language

Question 2

The main difference between C and C++ is that C++ is a strongly-typed language with object-oriented features.

Answer 2

False, C++ can be seen as a class-based C

Question 3

One of the weaknesses of C++ is that it requires the programmer to deal with too many low-level programming techniques. (T/F)

Answer 3

True

Question 4

Dictionaries are data structures that are more efficient at mapping one set of keys to a set of data than linked lists. (T/F)

Answer 4

True

Question 5

Unlike C or C++, Java does not have built-in dynamic data structures with pointers. (T/F)

Answer 5

True

Question 6

Since Java programs run on virtual machines, they run faster than equivalent C++ programs.

Answer 6

False

Question 7

If a program can be written in a scripting language, it will generally be much shorter than the same program written in C++

Answer 7

True

Question 8

One disadvantage of scripting languages is the lack of automatic memory management. (T/F)

Answer 8

True

Question 9

If your intention is to use scripting languages on a limited-memory console, then Lua is preferred over Python or Perl. (T/F)

Answer 9

True

Question 10

You should not use Lua if you do not want your program to pause during execution. (T/F)

Answer 10

True

Question 11

For rapid iteration in program development, scripting languages are preferred over C++ or Java. (T/F)

Answer 11

True

Question 12

While dynamic data structures provide versatility and save memory, arrays are simpler to program, and do not result in fragmented memory. (T/F)

Answer 12

True

Question 13

While dynamic data structures provide versatility and save memory, they are difficult to program and debug. (T/F)

Answer 13

True

Question 14

Bit packing is a technique used to save memory when floating-point numbers are used. (T/F)

Answer 14

False, Integers are also one of the reasons. It allows you to use less space when you don’t have the need for so many bits (such as an integer requiring 32 bits) to represent the range of values in which you are interested.

Question 15

Classes are abstract specifications of user-defined type that only allow one instance for each class. (T/F)

Answer 15

False, they allow as many instances as necessary

Question 16

Consider a scenario where there are three classes that are extensions of each other: Enemy, Boss, and Super-Duper Boss. The Boss is also an Enemy, and the Super-Duper Boss is a Boss. In this scenario, the Boss class is the parent of the Enemy class. (T/F)

Answer 16

False,it is a child

Question 17

One of the limitations of class inheritance is the unclear flow control between related entities. (T/F)

Answer 17

True
