Why the #define directive is used ? It defines array in C program It defines constants in C program It defines constructors in C program None of them

When an object goes out of scope, which functionality is called automatically ? Destructor Constructor Inline End of line

Destructors do not receive parameters and do not Initialized Compiled Return values None of them

Scope resolution operator is denoted by ? ? : ?? : :

A class data members and member functions belong to To that function scope That class scope To file scope All of the above

Passing arguments to a destructor, or specifying return type to destructor, causes No error Logical error Syntax error Runtime error Fatal error

A destructor for a class is denoted by Grave accent symbol ` Underscore _ Caret symbol ^ Tilde symbol ~

If no constructor is defined for a class, the compiler Start working with pointers Creates a function for constructor Creates a default constructor None of the above

A constructor that can be invoked with no arguments, is called as Empty constructor Inline constructor Default constructor None of them

Member selection operator is denoted by : > . . .

Non-member functions are defined as Class scope Function scope File scope Global scope

Member functions defined in a class definition are automatically Constructed Compiled Terminated Inlined

Constructors do not have Default value Initial value Return value, not even void None of them

Which operator accesses a structure member via the object’s variable name? Scope resolution operator Arrow member selection operator Dot member selection operator All of them

Which keyword is used for structure definition ? Structure_def Struct def_struct None of them

What is a class interface ? 1) It consists of member data declaration 2) It consists the definition of member functions 3) It consists of member function prototypes 4) Both 1 and 3

Member functions are also called 1) Services 2) Rational members 3) Methods Both 2 and 3

A class with only public members and no functions, are called C struct class C const class d_struct class None of them

Preventing access from outside the class is called Outsourcing Denying Information hiding None of them

Which function is called when an object reaches to the end of its scope? Access function Constructor Destructor None of them

Polymorphism is achieved by Operators Arrays Virtual function Constructors

Access functions that is used to test the truth or falsity of conditions, is called Private functions Public functions Predicate functions Protected functions

Which operator is combined with a pointer to an object to access that object’s member ? Scope resolution operator Arrow member selection operator Dot member selection operator All of them

Aggregate data types build using data of other types, is called as Structures Functions Pointers Elements

Sometimes a single value for a data member applies to all members of the class, for this purpose a Private data members are declared Static data members are declared Public data members are declared Variable data members are declared

The copy constructor is called automatically when An object is returned by value form a function An object is passes by value to a function An object is copied by means of a declaration initialization All of them

Local utility functions are called Public member functions Access functions Private member functions Protected member functions

Composition is also called as A)Containment B)Provision C)Aggregation D)Both A and C

When a data member of the new class is an object of another class, it is called as New class is a composite of other objects New class is inherited New class is aggregate of another None of them

We can define a new class from an existing class, by using A)Inheritance B)Composition C)Constructors D)Both A and B

An abstract base class is, that have One or more pure virtual member functions One or more child classes One or more functions All of them
