First,Registervariables keyword regiter requests the compiler to make the variables available to the CPU as much as possible in the register. Here are some points to note. The register variable must be a type that can be accepted by the

First of all, this project focuses on some basic knowledge and concepts in C + + practice, including: const type function, function return value, reference, class combination, and memory allocation.Write the code for each file directly below:date.h//

From today onwards, I began to learn C + +, finally to object-oriented programming (object Ah, I hope really can have an object). I am prepared to write a daily learning experience, to share to everyone, is a novice, words to express what aspects of

Fourth Chapter function semantics (the semantics of function)If there is a Point3D pointer and object:Point3D obj; Point3D *ptr = &obj; When doing this:Obj.normalize ();p tr->normalize (); , what happens? The Point3d::normalize () is defined as

Ladies and gentlemen, crossing, the last time we talked about the example of greatest common divisor, this time we say the example is: skillfully use shift. GossipHugh, the words return to the positive turn. Let's talk C chestnuts together!We talked

Smart pointers that are not smart at all#include using namespace Std;templateclass auto{public://to avoid compiler error, an explicit type conversion is required explicit Auto (t* data = NULL): m_data (data) {}//transfer copy Auto (auto&): m_data

STD map is an associative container for STL that provides a one-to-one (where the first can be called a keyword, where each keyword appears once in the map, and the second may be called the value of that keyword), and because of this feature, it's

In C + +, the memory layout of an object is consistent with the order of class member declarations, static members are placed in the data section instead of object memory, and if multiple class static member names are the same, C + + is renamed by

The types of values we use in general are: shaping and floating-point typeIntDouble, floatIn the calculation we should pay attention to defining variables, shaping the calculation back to integer, and floating-point calculation will retain 6 decimal
