Volatile is the meaning of "variable" and "unstable". Volatile is a keyword in C + + that resolves an issue that is prone to read errors in a "shared" environment. In a single-tasking environment, within a function body , if the statement

The user enters a string and then returns to the end. Because the length of the user's input is indeterminate, it is better to write the loops that you want to use. Write a code here yourself, inefficient, relatively speaking, if you can simulate

Object-oriented extension capabilitiesNote: When compiling a class, the compiler scans the class definition (without the body of the function) before scanning the class implementation (the function body of each member function, the initialization of

3.copy Constructor3.1copy constructor functionIt is a special constructor whose formal parameters are references to objects of this class. The function is to initialize a new object of the same type with an existing object.3.2general methods for

Ladies and gentlemen, crossing, the last time we were talking about file manipulation based on file pointers, this time we're talking about a file operation finale. Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing,

The concept of threadingThe thread's responsibility is to virtualize the CPU.The CPU provides the process-specific thread (functionally equivalent to the CPU) for each process, and if the application goes into a dead loop, the process will "freeze",

when we study the communication between C # threads, we find that there are about three traditional methods① global variables, it is easiest to use global variables because of the shared data space between multiple processes under the same process,

Copy Construction　　　　0 Initialization: The type name (), which is the value 0 for the base type, is an anonymous object for a class or struct type.When initializing a homogeneous new object with a homogeneous object, the call is naturally a copy

ObjectiveToday's C + + is no longer a simple "band-C" language, it has developed into a multi-lingual language of the composition of the language, where generic programming and based on its STL is the most brilliant part of C + + development. In

I. Overview: Iterator mode (Iterator), which provides a way to sequentially access various elements in an aggregated object without exposing the internal representation of the object.Two. Applicability:Access the contents of an aggregated object

In the case of a long socket connection, if the server or client has an exception, the other end of the socket dialog operation, the program will be unable to access the disposed object. For example, when the client has a problem to disconnect the

Pointers to pointers are a form of multilevel indirection, or a pointer chain. Typically, a pointer contains the address of a variable. When we define a pointer to a pointer, the first pointer contains the address of the second pointer, and the
