According to swig's ideas,C/C ++ is an excellent library-level code language, while Java, C #, and Python are dominant in writing

I could have explained all the reloads in one lecture. Because it was too late yesterday and very difficult, I only
The constructor initialization list begins with a colon, followed by a comma-delimited list of data members followed by an initialization in parentheses after each data member. For example:Class Cexample {Public:int A; float B; Constructor
Two class with pointer members (class String)1. Test code (use effect)int main () { string S1 (), string s2 ("Hello"); Constructor String S3 (S1); Copy construction cout 2 Big Three (three kinds of special
The shift between class and struct (struct) differs in that: By default, a class is derived and access is private, the struct's derivation and access rights is public.constructor Function The task of the constructor is to initialize the data
Object A in the Cbox class can be assigned directly to object B, regardless of whether the data members in the class are private or common. And a constructor is called when a is created, and B calls a different default constructor;1#include 2 using

Reference: http://www.weixueyuan.net/view/6348.htmlSummarize: The initialization of const member variables has only one path: the parameter initialization table.The const member function can use all member variables in the class, but cannot modify

In a class, if there is nothing, the class consumes 1 bytes, and once there are other space-occupying members in the class, the 1 bytes are not counted, such as a class with only one int that takes 4 bytes instead of 5 bytes. If there is only a
For normal types of objects, replication between them is simple, for example:int a=100;int b=a;And the class object is different from ordinary object, the inner structure of class object is generally more complex, there are various member variables.
Classes and structs are different, structs can be initialized with {...} method is all assigned, but what about the struct? One is to write an array of data into the same structure, and then the For loop uses a non-constructor to write to the class
The constructor initialization list begins with a colon, followed by a comma-delimited list of data members followed by an initialization in parentheses after each data member. For example:class? Cexample? {Public:???? int? A;???? float? b;????
I think the object-oriented children's shoes should not be unfamiliar with classes and objects!The object is not suddenly built, and the object must be created at the same time as the parent class and the object contained therein. C + + follows the
description of use of friend function1) The Friend function must be stated in the description of the class, stating that the friend function is preceded by a keyword friend, followed by a function prototype of the friend function, and that the
A function that is described in the class body is called a member function as a member of a class. A general member function, which is defined according to the needs of a certain kind of function. In addition, some special member functions are
When a member function in a class involves two objects, it is necessary to use the this pointer; Each member function, including the construct and destructor, has a this pointer. The this pointer points to the calling object, and if you need to
