Hello! |
What is the output of the following program? #include <iostream> using namespace std; class TestClass { public: TestClass(int x) {cout << x << endl;} TestClass() {cout << "Hello!" << endl; } }; int main() { TestClass test; return 0; } |
the class |
The constructor function always has the same name as ________. |
Identify objects, then define objects’ attributes, behaviors, and relationships |
The process of object-oriented analysis can be viewed as the following steps: |
only one |
A class may have this many default constructor(s). |
default constructor |
When a constructor function accepts no arguments, or does not have to accept arguments because of default arguments, it is called a(n) ________. |
private and public |
Examples of access specifiers are the key words: |
private access specifier |
This is used to protect important data. |
structure |
A C++ class is similar to one of these. |
subscripts |
Objects in an array are accessed with ________, just like any other data type in an array. |
private |
If you do not declare an access specification, the default for members of a class is ________. |
constructor, created |
A ________ is a member function that is automatically called when a class object is ________. |
attributes, methods |
In OOP terminology, an object’s member variables are often called its ________, and its member functions are sometimes referred to as its behaviors, or ________. |
myCar.accelerate(); |
Assume that myCar is an instance of the Car class, and that the Car class has a member function named accelerate. Which of the following is a valid call to the accelerate member function? |
inline |
When the body of a member function is defined inside a class declaration, it is said to be ________. |
Nothing. Destructors have no return type. |
The destructor function’s return type is ________. |
dot operator |
Members of a class object are accessed with the ________. |
-> operator |
When you dereference an object pointer, use the ________. |
data type |
A class is a(n) ________ that is defined by the programmer. |
data, functions |
Objects are created from abstract data types that encapsulate ________ and ________ together. |
None of these |
The constructor function’s return type is ________. int float char structure pointer |
77 |
What is the output of the following program? #include <iostream> using namespace std; class TestClass { public: TestClass(int x) {cout << x << endl;} TestClass() {cout << "Hello!" << endl; } }; int main() { TestClass test(77); return 0; } |
data, functions |
In a procedural program, you typically have ________ stored in a collection of variables, and a set of ________ that perform operations on the data. |
The program will not compile. |
What is the output of the following program? #include <iostream> using namespace std; class TestClass { private: int val; void showVal() { cout << val << endl; } public: TestClass(int x) {val = x;} }; int main() { TestClass test(77); test.showVal(); return 0; } |
z is available to code that is written outside the class. |
For the following code, which statement is not true? class Point { private: double y; double z; public: double x; }; |
#ifndef |
This directive is used to create an "include guard," which allows a program to be conditionally compiled. This prevents a header file from accidentally being included more than once. |
True |
True/False: Whereas object-oriented programming centers on the object, procedural programming centers on functions. |
False |
True/False: Class objects can be defined prior to the class declaration. |
False |
True/False: The constructor function may not accept arguments. |
False |
True/False: A destructor function can have zero to many parameters. |
True |
True/False: More than one constructor function may be defined for a class. |
False |
True/False: More than one destructor function may be defined for a class. |
True |
True/False: Object-oriented programming is centered around the object, which encapsulate together both the data and the functions that operate on the data. |
False |
True/False: You must declare all data members of a class before you declare member functions. |
False |
True/False: You must use the private access specification for all data members of a class. |
True |
True/False: A private member function is useful for tasks that are internal to the class, but is not directly called by statements outside the class. |
True |
True/False: If you do not declare a destructor function, the compiler will furnish one automatically. |
True |
True/False: When an object is defined without an argument list for its constructor, the compiler automatically calls the object’s default constructor. |
True |
True/False: One purpose that constructor functions are often used for is to allocate memory that will be needed by the object. |
True |
True/False: One purpose that destructor functions are often used for is to free memory that was allocated by the object. |
True |
True/False: When using smart pointers to dynamically allocate objects in C++ 11, it is unnecessary to delete the dynamically allocated objects because the smart pointer will automatically delete them. |
