这篇博客介绍了作者在Windows环境下首次尝试TCP通信的过程，包括客户端和服务端的实现，旨在通过实例提升技能。

很少去手写tcp通讯，而且windows上的tcp通讯更是没写过，写一下，练练手

客户端：

#include <iostream>
#include <string>
#include <winsock.h>
using namespace std;
#pragma comment(lib, "ws2_32.lib")

int main()
{
	WSADATA WSAdata;
	if (!WSAStartup(MAKEWORD(2, 2), &WSAdata))
	{
		cout << "初始化成功" << endl;
	}
	else
	{
		cout << "初始化失败" << endl;
		exit(1);
	}
	SOCKET send_sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
	if (send_sock == INVALID_SOCKET)
	{
		cout << "socket fail" << endl;
		exit(1);
	}

	//绑定
	SOCKADDR_IN send_addr;
	send_addr.sin_family = AF_INET;
	send_addr.sin_addr.S_un.S_addr = INADDR_ANY;
	send_addr.sin_port = htons(9090);
	if (bind(send_sock, (sockaddr *)&send_addr, sizeof send_addr) == SOCKET_ERROR)
	{
		cout << "bind error" << endl;
	}
	else
		cout << "bind ok" << endl;

	//建立连接
	SOCKADDR_IN server_addr;
	server_addr.sin_family = AF_INET;
	ser
