The key to the assignment operator is the handling of the self-assignment mechanism You need to consider self-assignment problems when overloading assignment operators, which can cause serious errors.fred& operator= (const fred& f){

1. Point P,int R:p (_p) {}Object P P.print ();//code reuse call the print function in point2. Object member variables, which do not appear initialized with the initialization list, the compiler will still automatically invoke the constructor

First, the compilation preprocessing:1. Macro definition : Start with #define, divided into two types with parameters and without parameters.Macro definition without parameters: #define PI 3.14Macro substitution is simply a simple substitution

What is a constructor function Constructors build objects from dust. They turn a pile of arbitrary bits into a living object. List x, List x () and list X (Bar ()) List x, declaring an object of type list named X, List X (),

1. Inline function Define can define macro code snippets, but C + + recommends using inline functions instead of macro snippets. int f (intint b) {}You only need to add the inline keyword before the function definition (implementation). An inline
