PPP

Question 1

abstract class

Answer 1

a class that cannot be directly used to creat objects; often used in defining an interface to derviced classes. A class is made abstract by having pure virtual function or protected constructor.

Question 2

address

Answer 2

a value that allows us to find an object in a computers memory

Question 3

algorithm

Answer 3

a procedure or formula for solving a problem; a finite series of computational steps to produce a result

Question 4

alias

Answer 4

an alternative way to referring to an object; often a name, pointer or reference

Question 5

argument

Answer 5

a value passed to a function or a template, in which it is accessed through a parameter

Question 6

assertion

Answer 6

a statement inserted into a program to state that something must always be true at this point in the program

Question 7

base class

Answer 7

a class used as the base of a class hierarchy. Typically has one or more virtual functions

Question 8

bit

Answer 8

basic unit or information, valued 0 or 1.

Question 9

byte

Answer 9

basic unit of addressing, typically holding 8 bits.

Question 10

class

Answer 10

a user defined type that may contain data members, function members, and member types.

Question 11

concrete class

Answer 11

a class for which objects can be created

Question 12

constructor

Answer 12

an operation that initializes an object. Typically establishes an invariant and often acquires resources needed for an object to be used.

Question 13

inveriant

Answer 13

something that must always be true at a given point of a program; typically used to describe the state (set of values) of an object or the state of a loop before entry into the repeated statement

Question 14

reference

Answer 14

a value describing the location of a typed value in memory (2) a variable holding such a value.

Question 15

container

Answer 15

object that holds elements (other objects)
ex:std::vector<int> myVector;</int>

Question 16

declaration

Answer 16

the specification of a a name with its type in a program

Question 17

definition

Answer 17

a declaration of an entity that allocates memory

Question 18

derived class

Answer 18

a class derived from one or more base classes

Question 19

destructor

Answer 19

an operation that is implicity invoked when an object is destroyed, often releases resources if made to do so.

Question 20

scope

Answer 20

the region of a program source code in which a name can be referred to.

Question 21

subtype

Answer 21

derived type; a type that has all properties of a type and possibly more

Question 22

supertype

Answer 22

base type; a type that has a subset of the properties of a type

Question 23

iteration

Answer 23

repetition of a task or activity
