질문 제목 : 서버와 클라이언트 연결하는게 잘 안돼요 ㅜㅠ

질문요약 : 소스를 좀 바꿨더니 바꾸기 전처럼 실행이 안돼요 ㅜㅠ

질문내용 :
처음에
클라이언트
#include stdio.h
#include winsock2.h
#include stdlib.h
#include string.h
#define BUFSIZE 256
#pragma comment(lib,ws2_32.lib)
int main(int argc,char* argv[])
{
SOCKET h_socket;
WSADATA wsa;

char message[BUFSIZE];
char serv_addr[BUFSIZE];
char serv_port[BUFSIZE];
FILE *fp;
SOCKADDR_IN SV_addr;
int ms_len;
printf(연결할 서버 주소를 입력하세요 :);
fgets(serv_addr, BUFSIZE, stdin);
printf(연결할 포트 번호를 입력하세요 :);
fgets(serv_port, BUFSIZE, stdin);

fp=fopen(receive.txt,w+);

if(WSAStartup(MAKEWORD(2,2), &wsa) !=0)
{
printf(WSAStartup error!\n);
}

h_socket = socket(AF_INET, SOCK_STREAM,0);
if(h_socket==INVALID_SOCKET)
{
printf(socket error!\n);
}

memset(&SV_addr,0,sizeof(SV_addr));
SV_addr.sin_family = AF_INET;
SV_addr.sin_addr.s_addr=inet_addr(serv_addr);
SV_addr.sin_port = htons((unsigned short)atoi(serv_port));

if(connect(h_socket, (SOCKADDR*)&SV_addr, sizeof(SV_addr)) ==SOCKET_ERROR)
{
printf(connect error!\n);
}

while((ms_len=recv(h_socket,message, BUFSIZE,0))!=0)
{
fwrite(message, sizeof(char), ms_len,fp);
}

fclose(fp);
closesocket(h_socket);
WSACleanup();
return 0;
}

이렇게 하면 연결이 잘돼는데...

이렇게 바꾸고 나서부터 연결이 안돼요 ㅜㅠ
그리구~ 이렇게 바꾸면 fgets부분도 안돼구요 ㅜㅠ 왜그럴까요~????

참고로 이건 서버 소스입니다~~
