Question

Which of the following base class members is never inherited by a derived class, regardless of access attributes? (Points : 4)
Mutator
Data
Accessor
Destructor


10. (TCO 5) If p is a dynamic array, which statement deallocates the memory occupied by p? (Points : 4)
delete p;
delete *p;
delete [p];
delete [] p


11. (TCO 5) Given the declaration:

int num = 6;
int *p = # (Points : 4)
p++;
(*p)++;
(*num)++;
p&num++;


12. (TCO 5) What will be the output of the following code snippet?

mydata->dval = 123.45;
mydata.dval = 123.45;

5. (TCO 6) If a class has pointer data members, it should (Points : 4)
overload the assignment operator and define the copy constructor.
not overload any operators.
overload only the assignment operator.
overload the assignment operator, but not define the copy constructor.


6. (TCO 6) Including the const keyword before the parameter of an overloaded operator will (Points : 4)
cause a compiler error.
prevent the operator from changing the value of the parameter.
prevent the operator from changing the value of the parameter only if it is an object of the same class in which the overloaded operator is defined.
only be used when overloading the assignment operator.


7. (TCO 7) Static binding is a process which is (Points : 4)
performed during run-time operation of the program.
performed during the linking operation of the program.
performed during the compilation of the program.
performed only when the static option is set in the compile options.


8. (TCO 7) Overriding a base class member function with a derived member function demonstrates the concept of (Points : 4)
overloading.
inheritance.
polymorphism.
abstraction.


9. (TCO 7) Virtual functions are reserved using what C++ keyword? (Points : 4)
Polymorphic
Static
Dynamic
Virtual


10. (TCO 7) If class Shape is an abstract class, what type of variable may be declared of type Shape? (Points : 4)
No variables may be declared because it is an abstract class.
Only arrays of the class Shape may be declared.
Objects of class Shape may be declared only if an object of a class derived from Shape is also declared.
A pointer of the abstract class may be declared.


11. (TCO 7) If a function is declared virtual in a base class then (Points : 4)
it must also be declared as virtual in any derived class.
it must not be overridden in any derived classes.
it remains virtual even if a derived class overrides it and does not declare it as virtual.
it must be overridden in any and all derived classes.


12. (TCO 8) In a multi-file, object-oriented C++ project, which file contains the class definition? (Points : 4)
classname.cpp
classname.h
classname.def
classname.hdr


13. (TCO 8) Which is a correct preprocessor directive statement? (Points : 4)
define PI = 3.141593
define PI = 3.141593;
#define PI 3.141593
#define PI = 3.141593


14. (TCO 8) Which preprocessor directive essentially inserts another file into your source file? (Points : 4)
ifndef
define
include
fstream

Explanation / Answer

Dear,

10) delete p;
11)In order to increment the num value
(*p)++;
12) The output of the following code snippet 10 10
13)mydata->dval = 123.45;
1)class bClass: public aClass{ //...};
2)++ operator overloads
3)fiend className operator++(int);
4)+ is unary operator
5)overload the assignment operator and define the copy constructor
6)prevent the operator from changing the value of the parameter
7) performed during the compilation of the program.
8) polymorphism.
9) Virtual
10) Objects of class Shape may be declared only if an object of a class derived from Shape is also declared
11)it must be overridden in any and all derived classes.
12) classname.cpp class definition
class declaration is done in classname.h
13)#define PI 3.141593
14) include

Hope this will help you.
