Exam 10: Defining Classes

Which of the following is the correct function definition header for the getAge function which is a member of the Person class?

Two different structure definitions may have the same member names.

A data type consisting of data members and operations on those members which can be used by a programmer without knowing the implementation details of the data type is called

If you have a class with a member function called displayostream& out), that will send the values in the class to the parameter stream, and you need to call that function from within another member function, how would you call it to print the data to the screen? ___________________________

When several items variables or variables and functions) are grouped together into a single package, that is known as ______________.

When a structure contains another structure variable as one of its members, it is known as a ___________________.

All constructors for a class must be private.

A structure can only be passed to a function as a call-by-value parameter

The assignment operator may not be used with objects of a class.

Given the following class definition and the following member function header, which is the correct way to output the private data? Class Person { Public: Void outputPersonostream& out); Private: Int age; Float weight; Int id; }; Void Person::outputPersonostream& out) { //what goes here? }

If class A is derived from class B, then B is a _______ of A.

A structure variable is a collection of smaller values called ____________ values

Given the following strucure definitions, what is the correct way to print the person's birth year? Struct DateType { Int day; Int month; Int year; } Struct PersonType { Int age; Float weight; DateType birthday; } PersonType person;

Given the following class, what would be the best declaration for a mutator function that allows the user of the class to change the age? Class Wine { Public: Wine); Int getAge); Float getCost); Private: Int age; Float cost; }

It is possible to have multiple private labels in a class definition.

A struct variable is declared differently from a predefined type such as an int.

A derived class is more specific than its parent, or base class.

Given the following class definition, how would you declare an object of the class, so that the object automatically called the default constructor? Class ItemClass { Public: ItemClass); ItemClassint newSize, float newCost); Int getSize); Float getCost); Void setSizeint newSize); Void setCostfloat newCost); Private: Int size; Float cost; };

The keyword ________ defines a structure type definition.

If you design a class with private data members, and do not provide mutators and accessors, then
