伺服器：

#include #include int main()		


if ( lobyte( wsadata.wversion ) != 1 ||


hibyte( wsadata.wversion ) != 1 ) 


socket srvier = socket(af_inet, sock_dgram, 0);


sockaddr_in addr_srv;


addr_srv.sin_family = af_inet;


addr_srv.sin_port = htons(6000);


addr_srv.sin_addr.s_un.s_addr = htonl(inaddr_any);


bind(srvier, (sockaddr *)&addr_srv, sizeof(addr_srv));


char rbuf[100];


char sbuf[100];


char tbuf[100];


sockaddr_in addr_cli;


int len = sizeof(addr_cli);


while (1)


sprintf(tbuf, "%s say : %s", inet_ntoa(addr_cli.sin_addr), rbuf);


printf("%s\n", tbuf);


printf("please input data:");


gets(sbuf);


sendto(srvier, sbuf, strlen(sbuf)+1, 0, (sockaddr *)&addr_cli, len); } 


closesocket(srvier);


wsacleanup();


return 0;


}

客戶端： 

#include #include int main()		


if ( lobyte( wsadata.wversion ) != 1 ||


hibyte( wsadata.wversion ) != 1 ) 


socket client = socket(af_inet, sock_dgram, 0);


sockaddr_in addr_srv;


addr_srv.sin_family = af_inet;


addr_srv.sin_port = htons(6000);


addr_srv.sin_addr.s_un.s_addr = inet_addr("127.0.0.1");


int len = sizeof(addr_srv);


char sbuf[100];


char rbuf[100];


char tbuf[100];


while (1)


sprintf(tbuf, "%s say: %s", inet_ntoa(addr_srv.sin_addr), rbuf);


printf("%s\n", tbuf);


} closesocket(client);


wsacleanup();


return 0;


}

時間程式（基於UDP）

server 需求 寫乙個時間同步的伺服器 服務端接收請求 按照client端傳送的時間格式,將伺服器時間轉換成對應格式 傳送給客戶端 import time import socket sk socket.socket type socket.sock dgram sk.bind 127.0.0....
