Derived classes in C + + have the following two types of access to base class Members:1. Internal access: accessed by a member of a derived class that is inherited by a new member of the base class.2. Object access: Outside the derived class, access

It is said that the famous Jewish historian Josephus had the following story: After the Roman occupation of Chotapat, 39 Jews and Josephus and his friends hid in a hole, 39 Jews decided to prefer to die and not be caught, so decided to a suicide way,

Clause 46 When you enter conversions, you need to define non-template member functions Clause 47 Please use the Traits class expression type information Clause 46: Defining a non-member function for a template when a type conversion is

1. In general, the arithmetic operator (hereinafter "celibacy") is overloaded, and the compound assignment operator (hereinafter "compound form") is overloaded. To ensure that the compound form of the operator, such as (operator+=) and celibacy (for

Implicit type conversion is a good and bad feature of C + +. It is convenient, but it can cause some very vague mistakes. Type conversions provide a type of construct to another type. Class X{public:operator int () const noexcept {return

1. Virtual constructorIn principle, constructors cannot be virtual: Virtual functions are used to implement "behavior that differs depending on type", that is, to invoke different entities based on the dynamic type of the pointer or reference to the

The C + + language provides programmers with a number of functions that make it very easy to handle character arrays. These functions allow you to copy, concatenate, compare, and find the character array.When an array is declared, C + +

Why to use STLThe separation of data structures (such as vectors) and the separation of algorithms (e.g., the STL sort () function is completely generic and you can use it to manipulate almost any data set, including linked lists, containers, and

One of the most important features of C++11 is the support of multithreading, but "C + + Primer" 5th does not have this part of the introduction, it is a bit regrettable. Learned something about the thread library on the web. Here are a few of the
