Once a numeric number is calculated, basically it is constantly splitting using 10. Re-count and see how many numbers there are.Today it is easier to think about converting numbers to strings and then getting the number of digits by

The structure of the implemented circular single-linked list is as follows:The implementation of the circular single-link list, and the implementation of a single linked list of the previous article is roughly the same click the Open link , slightly

RTTIBy using run-time types to identify--rtti, programs can use pointers or references to base classes to retrieve the actual derived class types of those pointers or references to the objects they refer to:It is mainly implemented by two operators:1

This time the code is longer, because it is more than the previous vector implementation of a lot of operations, and after all, the pointer operation, it is a little more cumbersome to handle.A very important point in the list implementation is to

Any data in memory is stored in binary form, such as a short data 1156, and a binary representation of 00000100 10000100. In the Intel CPU architecture of the system, the storage method is 10000100 (low address unit) 00000100 (High address unit),

Always feel that the function pointer is a difficult thing, in fact, the function pointer and the general pointer, quite simple.One, the definition of a function pointerA function pointer, as the name implies, is a pointer to a function, which is a

The structure of the implemented single-linked list is as follows:Header file: SList.h#include #include using namespace Std;typedef enum{false,true}status;templateclass List;templateclass listnode{friend class list; The friend class can access the

The AutoResetEvent object is used for thread synchronization operations, and the AutoResetEvent class inherits the WaitHandle class.The AutoResetEvent object has both terminating and non-terminating states, the terminating state is that the thread

First, the classification of functionsAs already mentioned, the functions in C are the "methods" in object-oriented, and the functions of C can be divided into 3 classes:1. The main function, which is the main function. There can be only one or one

Recommendation 105: Use private constructors to harden a single caseSingleton refers to a type that generates only one instance object. A simple implementation of the singleton is as follows: Static voidMain (string[] args)

Appearance mode-provides a unified interface for accessing a group of interfaces in a subsystem. The appearance defines a high-level interface to make the subsystem easier to use.　　A look contains a lot of objects and operations on them, making it

Iterator mode: Provides a way to sequentially access individual elements in an aggregated object without exposing their internal representations.　　The Pancake House and the restaurant are merged! But there was a small problem, although both agreed
