1. Pass value parameter (not pointer parameter): #include　 int　inc(int　x); int　main(void) { 　　int　num　=　1; 　　printf("%d\n",inc(num));　/*　2　*/ 　　printf("%d\n",num);　　　/*　1;　num　并没有改变,用作函数参数时只是复制过去　*/ 　　getchar(); 　　return　0; } int　inc(int　x)　{ 　

An application example of indefinite parameter in C language: indefinite parameters as a special skill of the middle-C + + language was praised by many people, but in fact this technology has not been applied much. I don't see much application

In C language applications, such as communications and embedded systems, a software project usually contains a lot of complex functions, to achieve this project is not a programmer alone can be competent, often need a team of effective cooperation,

1 Socket in POCO The POCO is rich in Socket encapsulation. Its inheritance relationship is as follows: This article only introduces Streamsocket, ServerSocket, Datagramsocket 2 Poco::net::serversocket A serversocket is a Socket with a lower

The purpose of the new feature The right value reference (Rvalue referene) is a new feature introduced in the new C + + standard (c++11, 11 for 2011), which implements the transfer semantics (move sementics) and precise delivery (Perfect forwarding)

From the point of view of program flow, the program can be divided into three kinds of basic structure, namely sequential structure, branch structure and cyclic structure. These three basic structures can be composed of all kinds of complex programs.

Determines whether a particular character is a ASCII character. int __isascii( int c ); int iswascii( wint_t c ); Test program: #include "stdafx.h" #include "ctype.h" #include "locale.h" #include "stdio.h" void CheckCharAndPrint(char acChar) {

Double-linked list each data node has two pointers, pointing to its successor and the predecessor node respectively. It is more flexible than a single linked list can only access its successor node, and of course it takes up more storage space. The

The game handles the programming development in two, has explained, in this article will explain to the keyboard simulation. The simulation of the keyboard, the system has provided a lot of API functions, here is not one to explain, only the

The title of the popular point, however, this is also a lot of people appear after this ghost, the most intuitive feeling. A few days ago to help the Sadie community a friend of the recovery, his situation and the previous case is very similar to

As the world's top mathematical application software, MATLAB plays an increasingly important role in the fields of aerospace, mechanical manufacture and engineering construction, with its powerful engineering calculation, algorithm research,

1. Overview A variable of a static declaration has two characteristics in the C language: 1), the variable will be placed in the program's global storage area, so that the next time the call can also maintain the original assignment. This is how

First of all, for an inheritance system, the constructor is invoked from the base class, and the destructor is just the opposite, starting with the outermost class. For a call to the virtual function in the constructor, give an example: 1 class

Initialization of two-dimensional arraysTwo-dimensional array initialization is also assigned an initial value to each subscript variable in the type description. Two-dimensional arrays can be assigned in rows or rows, and can be assigned

Enum (enum) Enumerations are a collection of named Integer constants, which are common in everyday life.For example, the sunday,monday,tuesday,wednesday,thursday,friday,saturday of the week is an enumeration.The descriptions of enumerations are
