Transferred from: Http://www.jianshu.com/p/213b3b96cafeObjective:In the work, many small partners will PCH define some common macros in the file, but also afraid to write these simple macro waste of time, and sometimes forget how to define how to do? I am also in the work of the same. So here to share some common macro definitions, like the small partners can be used directly in the project (continuous update)!For the convenience of everyone, please c

created from a class. Declares an object of a class, just like a variable that declares a primitive type. The following statement declares the two objects of a class Box:Box Box1; // declaration Box1, type Box Box Box2; // declaration Box2, type BoxBoth objects Box1 and Box2 have their own data members.Accessing data membersThe public data members of the object of the class can be accessed using the direct member access operator (.). To better understand these concepts, let's

When writing a Graph template class, in order to enable the user to customize the type of distance, such as int or double or even other high-precision rational number encapsulation class,I defined the type of distance as template parameter t_dist and used library functions in the standard librarySTD :: numeric_limits t_dist : : Max ()To define the maximum distanceTemplateTypeName t_dist>ConstTypeNameTopologicalgrapht_dist: :DistanceTopologicalgrapht_dist: :max_distance= (STD::numeric_limitst

In "/sys/types.h", there are the following:1 #include 2#ifndef __pid_t_defined3 typedef __pid_t pid_t; 4 101 # define __pid_t_defined 5 102 #endifObviously, pid_t is just a __pid_t alias. Or, the pid_t type is actually the __pid_t type.2. In "Bits/types.h", there are the following:1 /*We want __extension__ before typedef ' s that use nonstandard base types2 118 such as ' Long ' in C89

the class member default access level, from the "feel", most programmers think they are still different: "struct" is just like a bunch of open memory bits of lack of encapsulation, more often it is used to represent more complex data; Class "is more like a live and reliable reality entity, it can provide services, have a strong encapsulation mechanism, and a well-defined interface. Since everyone is so "feeling", the "struct" keyword is used to declare a class only if the class has only a few m
