C++ Programming (2) Flashcards
What are preprocessor directives?
How can preprocessor directives be used to prevent multiple inclusion of the same header file?
what is the syntax of the #define preprocessor directive? What does it do? What are some other preprocessor directives?
What are namespaces? What is the syntax for declaring a namespace?
Example of defining a namespace. How are things within a namespace accessed?
How do we declare what default namespace we are using?
Should you include the ‘using namespace …’ syntax in a header file? Why?
What is the standard library for input and output in C++? What are two commonly used output stream objects in C++? Common input stream?
Are the standard inout and output functions from C also available in C++?
Are C++ I/O operators performed by functions or operators?
What are the insertion / extraction operators? What is the only thing you can put on the right of the extraction symbol?
Insertion and Extraction example:
What happens with the extraction operator when erroneous data is passed?
When using the extraction operator to read input characters into a string variable, how are leading whitespace characters treated?
Limitations of Extraction example:
How can we parse a line and extract the type / date from it?
How can we read from/write to files? What is the library called?
What work is generally done with files in C++?
Classes are an expanded concept of ___.
Classes contain what?
What is an object?
How are classes defined?
What are the different components of a class definition?
What is the general format of having a main C++ file, a C++ class file, and a C++ header? Where would you put the ‘using namespace’ line?
How do you compile all C++ files to create an executable?
What are access specifiers? What is the difference between private, public, and protected?
Access specifiers example:
How are objects created? Is an object created when a variable pointing to a class type is created?
How do you create an object with a pointer variable? What are the steps within the statement?
When are objects created on the stack destroyed? What about objects created dynamically? How are dynamically created object destroyed?
What is a constructor? Are they required?
What is a copy constructor? What can it be used for?
What happens if you do not declare a copy constructor?
What is a destructor? When is it called?
What is class inheritance? What does it allow us to do? What is a base/superclass? Derived/subclass?
How many classes can a class derive itself from? How do we define a derived class?
Inheritance example:
How does inheritance work alongside access specifiers?
Inheritance and access specifiers example:
How does inheritance of constructors and destructors work?
Inheritance of constructors and destructors example:
What is multiple inheritance? How does it work?
What is a ‘Friend’ of a class?
What are ‘Friend’ functions?
What are ‘Friend’ Classes?
