基于TCP的字符聊天VC+程序

1、服务器端：#include #include stdio.hvoid main()WORD wVersionRequested;WSADATA wsaData;int err;wVersionRequested = MAKEWORD( 1, 1 );err = WSAStartup( wVersionRequested, &wsaData );if ( err != 0 ) return;if ( LOBYTE( wsaData.wVersion ) != 1 |HIBYTE( wsaData.wVersion ) != 1) WSACleanup( );return; /上面代码为与操作系统

2、协调要使用的winsocket版本SOCKET apaserver=socket(AF_INET,SOCK_STREAM,0);/创建了一个服务器端的套接字sockaddr_in apaaddr;apaaddr.sin_addr.S_un.S_addr=htonl(INADDR_ANY);/inet_addr(192.168.0.10);apaaddr.sin_family=AF_INET;apaaddr.sin_port=htons(6000);/apaaddr.sin_zero=bind(apaserver,(sockaddr*)&apaaddr,sizeof(sockaddr);/将套接

3、字与IP地址和端口绑定listen(apaserver,5);/设置套接字为监听模式sockaddr_in apaclient;int n=sizeof(sockaddr);char m100;char j100;char buff200;SOCKET apaconnect=accept(apaserver,(sockaddr*)&apaclient,&n);/建立“连接套接字”while(1)char tone100;int t;t=recv(apaconnect,j,100,0);/从客户端接收到的字符存入b缓冲区*if(t=SOCKET_ERROR)printf(对方结束了本次通话n);

4、break;printf(客户端发来信息:n);printf(%sn,j);/在屏幕上显示了客户端所说的话printf(服务器请讲话：);gets(tone);/服务器端的发送功能send(apaconnect,tone,strlen(tone)+1,0);/printf(服务器端完成一次运行n);closesocket(apaconnect);WSACleanup();客户端：#include #include stdio.h#include void main()/WORD wVersionRequested;WSADATA wsaData;int err;wVersionRequeste

5、d = MAKEWORD( 1, 1 );err = WSAStartup( wVersionRequested, &wsaData );if ( err != 0 ) return;if ( LOBYTE( wsaData.wVersion ) != 1 |HIBYTE( wsaData.wVersion ) != 1) WSACleanup( );return; SOCKET user=socket(AF_INET,SOCK_STREAM,0);SOCKADDR_IN QQ;QQ.sin_addr.S_un.S_addr=inet_addr(127.0.0.1);QQ.sin_family

6、=AF_INET;QQ.sin_port=htons(6000);connect(user,(SOCKADDR*)&QQ,sizeof(SOCKADDR);char c100;char str100;char b100;while(1)int t;printf(请输入你要说的话：);gets(str);send(user,str,strlen(str)+1,0);t=recv(user,b,100,0);/从客户端接收到的字符存入b缓冲区*/客户端的接收功能if(t=SOCKET_ERROR)/printf(对方结束了本次通话n);break;printf(服务端发来信息：);printf(%sn,b);/* printf(客户端完成一次运行n);/closesocket(user);WSACle
