I think the comments are detailed, haha.//namespaces use example. cpp #include using namespace std; Space STD covers all standard C + + definitions and declarations namespace one//defines a namespace one with 1 constants m and a variable inf {const

#include class a{ A () { printf ("a constrution.\n"); } ~a () { printf ("A deconstrution.\n"); } void Funa (); Virtual void Funb ();}; void A::funa () { printf ("A::funa ... \ n");} void A::funb ()

First, overloadOccurs in the same class, when method A is defined in the same class, and then the method b,b and a are defined with the same name, but the parameters are different, then the B overloads the method A.class test{public: void A ();

1. What is a comment1) Annotations are a concept that is very important in all computer languages, literally, the meaning of annotations and explanations. 2) Comments can be used to explain the meaning of a program or a line of code to facilitate

In some cases, we want to infer the type of the variable to be defined from the type of the expression, but do not want to initialize the variable with the value of the expression. The second type descriptor Delctype introduced by C++11 is used to
