Definition Class In C++, the class is the construct primarily used to create objects.

Definition OBJECT Objects are instances of a class.

Definition Encapsulation

Definition Constructor A constructor is a member function that is automatically called when a class object is created. Default constructor A constructor that has no parameters.

Definition Friend of classes A friend is a function that is not a member of a class, but has access to the private members of the class.

Definition Memberwise Assignment The = operator may be used to assign one object to another or to initialize the object with another object’s data. By default, each member of one object is copied to its counterpart in the other object.

Definition Copy Constructor A copy constructor is a special constructor that is called whenever a new object is created and initialized with the data of another object of the same class Ex: Car (Car a) { myYear = a.getYear(); myMake = a.getMake(); }

Which of the following shows the correct use of the scope resolution operator in a member function definition? InvItem:: void setOnHand (int units) Void InvItem:: setOnHand (int units)

Assuming that soap is an instance of an Inventory class, which of the following is a valid call to the setOnHand member function Inventory soap; setOnHand(20); soap::setOnHand(20); soap.setOnHand(20); Inventory.setOnHand(20);

A private class member function can be called by Any other function Only public functions in the same class Only private functions the same class Any function in the same class

Assume a map class has a member variable named position that is an instance of the Location class. The Location class has a private member variable named latitude and a public member function called getLatitude. How would you return the value stored in latitude return Location.latitude(); return Location.getLatitude(); return position.latitude();

Assume there is a class named Pet Assume there is a class named Pet. Write the prototype for a member of Pet that overloads the = operator. Pet Pet :: operator= (Pet);

What is the output for the following: try { …. throw (99); … } catch (int e) { cout << “The exception caught is : “ << e << endl; } cout << “ The code ran without exception “ << endl;

What is the output for the following: try { …. throw “ Bad input”; … } catch (int e) { cout << “The exception caught is : “ << e << endl; } cout << “ The code ran without exception “ << endl;

What is the output for the following: try { …. throw “ Bad input”; … } catch (int e) { cout << “The exception caught is : “ << e << endl; } catch (string se) { cout << The exception caught is “ << se << endl;} cout << “ The code ran without exception “ << endl;

What is the output for the following: try { …. throw (99); throw “ Bad input”; … } catch (int e) { cout << “The exception caught is : “ << e << endl; } catch (string se) { cout << The exception caught is “ << se << endl;} cout << “ The code ran without exception “ << endl;

Complete the following code skeleton to declare a class called DATE Complete the following code skeleton to declare a class called DATE. The class should contain member variables and functions to store and retrieve the month, day, and year components of a date Class Date {private: public: }
