(TCO 2) Given: bool clockType::equalTime(const clockType&) const {...} void clockType::getTime(int&, int&, int&) const {...} The word _____ at the end of the member functions in the class clockType specifies that these functions cannot modify the member variables of a clockType object. (Points : 4)

void const clockType:: &

+ - # $

Question 5.5. (TCO 2) Consider the following class definition. class circleType { public: void set(double r); //Postcondition: radius = r; void print(); //Output radius, area, and circumference. double area(); //Postcondition: Calculate and return area. double circumference(); //Postcondition: Calculate and return circumference. circleType(); //Postcondition: radius = 0; circleType(double r); //Postcondition: radius = r; private: double radius; }; and the declaration circleType myCircle; double r; Which of the following statements are valid in C++? (i) cin >> r; myCircle.area = 3.14 * r * r; cout (ii) cin >> r; myCircle.set(r); cout (Points : 4)

Only (i) Only (ii) Both (i) and (ii) None of these

Question 2.2. (TCO 3) What is the correct statement for declaring an array of 10 objects of ClassB? (Points : 4)

ClassB[10]; ClassB->objectB[10]; ClassB objectB[10]; objectB = new [10] ClassB;

Question 3.3. (TCO 4) Single inheritance means (Points : 4)

that the derived class is derived from a single base class. that only multiple classes can be derived from the given base class. that only one base class can be derived. single inheritance is not possible in C++.

Question 4.4. (TCO 4) If the derived class does not override a public member function of the base class, you may specify a call to that public member function that has parameters by (Points : 4)

using the name of the function and no parameter list. using only the name of the function. using the name of the function and the appropriate parameter list. Public member functions cannot be accessed in a derived class.

Question 5.5. (TCO 4) Which of the following is true about a derived class? (Points : 4)

A derived class can directly access any member variable of the base class. A derived class can redefine any public member function of the base class. A derived class can have at most one base class. A derived class can redefine any member function of the base class.

Question 6.6. (TCO 4) OOP implements _____. (Points : 4)

UML IPE EIP OOD

Question 7.7. (TCO 4) If class AClass is derived from class BClass, which one of the following statements correctly states the constructor call sequence when an object of AClass is instantiated? (Points : 4)

BClass constructor first, AClass constructor second AClass constructor first, BClass constructor second BClass constructor only; the AClass constructor is not called if AClass derived private from BClass AClass constructor only; the BClass constructor is not called if BClass derived private from AClass

Question 8.8. (TCO 4) If class AClass is derived from class BClass, which one of the following statements correctly states the destructor call sequence when an object of AClass goes out of scope? (Points : 4)

BClass destructor first, AClass destructor second AClass destructor first, BClass destructor second BClass destructor only; the AClass destructor is not called if AClass derived private from BClass AClass destructor only; the BClass destructor is not called if BClass derived private from AClass
