Exam 13: Introduction to Classes

A __________ is a member function that is automatically called when a class object is __________.

What is the output of the following program? #include <iostream> using namespace std; class TestClass { Public: $\quad$ TestClass(int x) $\quad$ { cout << x << endl; } $\quad$ TestClass() $\quad$ { cout << "Hello!" << endl; } }; int main() { $\quad$ TestClass test(77); $\quad$ return 0; }

A private member function is useful for tasks that are internal to the class but it is not directly called by statements outside the class.

The following code shows an example of __________ class Point { Private: Double y = 5.70; Double z = 3.0; Public: Public member functions go here... };

If a local variable and a global variable have the same name within the same program, the __________ resolution operator must be used.

When the body of a member function is defined inside a class declaration, it is said to be

You must declare all data members of a class before you declare member functions.

A class is a(n) __________ that is defined by the programmer.

When a member function is defined outside of the class declaration, the function name must be qualified with the

More than one destructor function may be defined for a class.

What is the output of the following program? #include <iostream> Using namespace std; Class TestClass { private: $\quad$ int val; $\quad$ void showVal() $\quad$ { cout << val << endl; } public: $\quad$ TestClass(int x) $\quad$ { val = x; } }; int main() { $\quad$ TestClass test(77); $\quad$ test.showVal(); $\quad$ return 0; }

Members of the class object are accessed with the

The constructor function's return type is

The constructor function may not accept arguments.

The type of member function that may be called from a statement outside the class is

In-place member initialization no longer is available in C++11.

You must use the private access specification for all data members of a class.

In object-oriented programming, the object encapsulates both the data and the functions that operate on the data.

Whereas object-oriented programming centers on the object, procedural programming centers on functions.

Which of the following is used to protect important data?
