基于TCP面向连接的socket编程。运行出错，一直出现 “烫”字。用的vs2010

#include <winsock2.h>
#include <stdio.h>
//服务器端程序
void main()
{
WORD wVersionRequested;
WSADATA wsaData;
int err;

wVersionRequested = MAKEWORD( 1,1 );
//加载Ws2_32.dll
err = WSAStartup( wVersionRequested, &wsaData );
if ( err != 0 ) {
return;
}

if ( LOBYTE( wsaData.wVersion ) != 1 ||
HIBYTE( wsaData.wVersion ) != 1) {
WSACleanup( );
return;
}

SOCKET SocketSrv=socket(AF_INET,SOCK_STREAM,0 );//step1 建立套接字
SOCKADDR_IN AddrSrv;
AddrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);//网络字节序
AddrSrv.sin_family=AF_INET;
AddrSrv.sin_port=htons(6000);//端口号两个字节
bind(SocketSrv,(SOCKADDR *)&AddrSrv,sizeof(SOCKADDR));//step2 绑定到套接字
listen(SocketSrv,5);//step3 监听连接请求 5为队列长度
SOCKADDR_IN AddrClient;
int len=sizeof(SOCKADDR);//必须赋初值
//服务器端程序循环运行
while(1)
{
SOCKET ScoketConn=accept(SocketSrv, (SOCKADDR*)&AddrClient, &len);//step4 接受请求 AddrClient接收连接请求方的信息
char SendBuf[100];
sprintf(SendBuf,"Wellcome! Connect from %s Success!",inet_ntoa(AddrClient.sin_addr));
send(ScoketConn,SendBuf,strlen(SendBuf)+1,0);//step5 发送数据用连接的套接字不能用处于监听状态的套接字
char RecvBuf[100];
recv(ScoketConn,RecvBuf,100,0);//step5 接收数据
printf("%s\n",RecvBuf);
closesocket(ScoketConn);
}
//实际上还需做以下操作 但上述是死循环因此没有执行下述操作
//closesocket(SocketSrv);//关闭套接字
// WSACleanup();//终止库引用
}

closesocket(SocketClient);//关闭套接字 释放资源
