不明白为什么会发生这个错误，求大神指点！具体代码如下
#pragma comment(lib,"ws2_32.lib")//第二版本32位的把lib文件添加到项目中windows套接字的动态链接库
#include<stdio.h>
#include<stdlib.h>
#include<WinSock2.h>

if((Ret=WSAStartup(MAKEWORD(2,2),&wsaData))!=0)
{

system("pause");
return;
}
if((ListeningSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP)==INVALID_SOCKET)) //使用if判断是否创建成功
{
