Concept: C++In, under the same scope, the same function name and different parameter lists constitute an overload Overloaded functions are usually used to name a group of functions with similar functions, which reduces the number of function names, It avoids the pollution of namespace and is of great benefit to the readability of the program. ...

1.list memory structure List is a two-way linked list, and the elements are not stored continuously in memory. It will request and release the space of an element every time it inserts and deletes an element. 2. Capacity operation functionfunctionbool empty()Check whether the container is emptysize_t size()Returns the number of elements in ...

C + + object oriented programming (4) 1. Basic concepts of operator overloading Operator overloading is to give multiple meanings to existing operators (predefined operators in C + +), so that unified operators can lead to different types of behavior when used for different types of data. The purpose of operator overloading is to expand the ...

features libev is a lightweight event driven library written in C language, which supports a variety of IO reuse interfaces. IO interfaces include: select, poll, epoll, kqueue, etc Supported events: ev_io; //IO read / write ev_stat; //File properties ev_signal;//signal ev_timer;//timer ev_periodic;//Absolute timer ev_child;//Subprocess ev_fo ...

1, What is an initialization list? There are two ways to initialize member variables of C + + classes. The first is in the constructor function body of the class, and the other is through the initialization list. For example: Initialize in constructor body: class Person { public:     Person()     {         name = 0;         age = 0;     } pr ...

c + + inheritance Inheritance allows us to define a class based on another class, which makes it easier to create and maintain an application. This also achieves the effect of reusing code functions and improving execution time. When creating a class, you do not need to rewrite new data members and member functions. You only need to specify tha ...

The abstract data type of linear table is defined in the sequential table storage structure and implemented by C + + class. Its template mechanism is as follows. const int MaxSize = 100; template <typename DataType> class SeqList { public: SeqList( ); //Create an empty sequence table SeqList(DataType a[ ], int ...

Three storage representations of 1 string      String, i.e. string. It should be noted that there is no string data type in C language, but it is implemented as a data structure - "content limited linear table", and the concepts of empty string, blank string, string length, substring and main string are agreed [se ...
