Question 7
2 pts
(TCO 5) Consider the following class definition and the object instantiation.

class House
{
     private:
    int age;
     double salesPrice;

     public:
    House()
     {
          age = 1;
          salesPrice = 2.0;
     }
    House(int a, double sp)
     {
          age = a;
          salesPrice = sp;
     }

    int getAge()
     {
         return age;
     }
    double getSalesPrice()
     {
         return salesPrice;
     }
    ~House() { }
} ;
int main()
{
      int tempAge=0;
    int tempPrice=0;

      House ranch();
return 0;
}

Using the main() method to access the members of the object, which of the following statement is correct?

tempPrice = House.SalesPrice();

ranch.age = 3;

cout<<”The house price is: “ << ranch.SalesPrice();

ranch.salePrice = 250000.0;

Question 8
2 pts
(TCO 2) Can two classes each define a method with the same name?

Yes, this is possible.

No, this is not possible because the compiler would not know which method to call.

Yes, but only if the classes have the same name.

Yes, as long as the method has the same number of parameters in each class.

Question 9

Check for potential problems and abort the application when a problem is encountered.

Question 10
2 pts

numberOfCars

None of the above

Explanation / Answer

1. private
2.None of the above correct amswer is accessors and mutators
3.The implementation is totally hidden from the user.

4.Only B and C

customer should respond to these two questions.

“How would you like your steak? Rare, medium rare, or well done?”

“What would you like to eat?”
5. A ___constructor__ initializes a newly created object, while a ___destuctor__ releases back the resources to the system when an object is not used anymore.
6. ans:public int Add(int x) ; public int Add(int y)

C++ allows specification of more than one function of the same name in the same scope. These are called overloaded functions and are described in detail in Overloading. Overloaded functions enable programmers to supply different semantics for a function, depending on the types and number of arguments.
7.

The class data members can be accessed only through setter and getter functions. The getAge() and getSalesPrice() are getter functions given in the program.

To display the value of SalesPrice, the cout statemet is cout<<”The house price is: “ << ranch.getSalesPrice();

*NOTE: in the options, change ranch.SalesPrice(); to ranch.getSalesPrice(); as the setter function name given in the program is getSalesPrice();.

Hence, the correct option will be cout<<”The house price is: “ << ranch.getSalesPrice();

8.Yes, this is possible

two different classes with same function name is very much possible because the two functions will be called by creating objects of classes .

if one class is inherited by another class then there may be ambiguity which function should be invoked.in this case answer will be No, this is not possible because the compiler would not know which method to call.
