#Socket

本文介绍了使用C++进行Socket编程的基本步骤，包括创建服务器端和客户端的实现过程。服务器端涉及监听、接受连接请求，客户端则涉及连接服务器并发送数据。通过实例详细解析了Socket通信的关键代码和流程。

服务器端:

#include <sys/types.h> 
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
#include <stdio.h>
#include <iostream>
#include <arpa/inet.h>
#include <unistd.h>

using namespace std;

typedef unsigned char uchar;

int main()
{
	//build the socket for server
	int s = socket(AF_INET, SOCK_STREAM, 0);
	//bind the socket to address
	struct sockaddr_in adr_s;
	adr_s.sin_family = AF_INET;
	adr_s.sin_addr.s_addr = inet_addr("127.0.0.1");
	adr_s.sin_port =htons(1235);
	bind(s, (struct sockaddr *)&adr_s, sizeof(adr_s));
	//listen
	listen(s, 20);
	//accept the request from client
	//build the socket for client, system can bind local address to it automatically
	struct sockaddr_in adr_c;
	socklen_t c_size = sizeof(struct sockaddr_in);
	int c=  accept(s, (struct sockaddr *)&adr_c, &c_size);

	/*
	char str[] = "Hello World!";  // apply for a space for the received data
	int recv_resu
