请问大家，这个文件的头文件要怎么写

#include<stdio.h>
#include<stdlib.h>
#include <WINSOCK2.H>
#include <STDIO.H>
#pragma comment(lib,"ws2_32.lib")
class FileHelper
{
private:
FILE *f;
char path_buffer[_MAX_PATH];
char drive[_MAX_DRIVE];
char dir[_MAX_DIR];
char fname[_MAX_FNAME];
char ext[_MAX_EXT];
public:
FILE * selectfile()
{
printf("请输入要传送的文件名\n");
scanf("%s",path_buffer);
if (f=fopen(path_buffer,"rb"))
{
printf("文件打开成功\n");
return f;
}
else
{
printf("文件不存在，请重新输入\n");
return selectfile();
}
}
char * getFileName()
{
_splitpath(path_buffer, drive, dir, fname, ext);
return strcat(fname, ext);
}
FILE * createFile(char *name)
{
remove(name);
if (f = fopen(name, "ab"))
{
printf("文件创建成功\n");
}
else
{
printf("文件创建失败\n");
}
return f;
}
bool createDir(char *dir)
{
char head[MAX_PATH] = "md ";
return system(strcat(head, dir));
}
};

😂救救孩子吧
