求助解决socket编程问题（内附我的源程序）

[cyang7891011]

这是我写的一个简单通信程序，但是调试不同，请各位大侠指点一下，我的qq号是308239941，请各位高手多多帮助，小弟在这谢谢了！！！
#include <stdio.h>
#include <string.h>
#include <winsock2.h>
#include <stdlib.h>
int main()
{
SOCKET sockfd,clientfd;
sockaddr_in addr;
sockaddr_in remote_addr;
int sin_size=sizeof(remote_addr);
sockfd=socket(AF_INET,SOCK_STREAM,0);
if (sockfd==SOCKET_ERROR)
{
printf("socket创建出错");
return 1;
}
addr.sin_family=AF_INET;
addr.sin_port=htons(5055);
addr.sin_addr.s_addr=INADDR_ANY;
//memset(&(addr.sin_zero),0,size(addr.sin_zero));
if(bind(sockfd,(struct sockaddr*)&addr,sizeof(addr)) ==SOCKET_ERROR)
{
printf("bind出错");
return 1;
}
if(listen(sockfd,2)==SOCKET_ERROR)
{
printf("listen出错");
return 1;
}
while(1)
{
clientfd=accept(sockfd,(struct sockaddr *)&remote_addr,&sin_size);
if(clientfd==INVALID_SOCKET)
{
printf("accept出错");
break;
}
}
//printf("Accepted client: %s:%d\n",
// inet_ntoa(client.sin_addr), ntohs(client.sin_port));
printf("receive a connection from %s\n",inet_ntoa(remote_addr.sin_addr));
if(send(clientfd,"Hello!",6,0)==-1)
{
printf("send出错");
//close(client_fd);
return 1;

}
closesocket(sockfd);
return 0;
