14. Classes and functions 类和函数 14.1. Time 时间 As another example of a user-defined type, we’ll define a class called Time that records the time of day.
In this example, class Rectangle is a friend of class Square allowing Rectangle's member functions to access private and protected members of Square. More concretely, Rectangle accesses the member variable Square::side, which describes the side of the square. There is something else new in this ...

The comparison method implemented in the comparer must be consistent and apply a total ordering so that when the comparison function declares equality for two items, it is absolutely true and not a result of one item not being greater than another or one item not being less than another. Note...
I think that if the method in OtherClass that you want to override in A and B is NOT virtual, then the override is not implicit. I believe there's a way to Explicitly override the functions, look that up. Share Follow answered Jan 24, 2011 at 17:53 Argote 2,15511 gold badge151...
Up to this point, we have been defining functions, structs, and classes in the outermost scopes (i.e. the module scope). They can be defined ininner scopes as well. Defining them in inner scopes helps with encapsulation by narrowing the visibility of theirsymbols, as well as creating clos...
Thisrefers to both functions and subroutines. A function member is also called a method. A class’ constructor is a special type of method. We discuss constructors in detail later in this chapter. Property members Aproperty member is implemented as a Private member variable together with a spec...
However, there is a feature in C++ calledfriend functionsthat break this rule and allow us to access member functions from outside the class. Similarly, there is afriend classas well, which we will learn later in this tutorial. friend Function in C++ ...
We typedef CTest to void. This way we can use "CTest *" in our C code as if it's a normal C type, whilst we have compile-time type checks (sort of at least :-)), and it's cleaner than always using "void *" 2. The use of "extern "C" { }" around all functions (both ...
