      a class object is the same as a class member.
      a class object is the same as a class access specifier.
      a class object is the same as a nonmember function.

2. (TCO 2) In C++, the mechanism that allows you to combine data and the operations on those data in a single unit is called a(n) _____. (Points : 4)       enumeration
      class
      member
      struct

3. (TCO 2) Given:

bool clockType::equalTime(const clockType&) const {...}
void clockType::getTime(int&, int&, int&) const {...}

      const
      clockType::
      &

4. (TCO 2) A class and its members can be described graphically using a notation known as the _____ notation. (Points : 4)       OON
      OOD
      UML
      OOP

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

      define PI = 3.141593;
      #define PI 3.141593
      #define PI = 3.141593

9. (TCO 8) What is the namespace commonly used with <iostream>? (Points : 4)       std
      standard
      .h
      cin and cout

using namespace std; (Points : 4)       using, namespace, and std
      using and namespace
      using
      namespace In C++ terminology, a class object is the same as a class instance. a class object is the same as a class ember. a class object is the same as a class access specifier. a class object is the same as a nonmember function. In C++, the mechanism that allows you to combine data and the operations on those data in a single unit is called a(n) _____. enumeration class member struct 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.

Explanation / Answer

And for number 8 its #define PI 3.141593

I accidently copied one with "="
