c++编程问题？

[Enna]

怎样用c++语言编写一段程序，比较两个文件（包括属性，时间，作者名等等。）是否相同。

这个得用到系统调用吧，取决于你的系统是什么，例如unix/linux 可以用stat或fstat //#include<sys/stat.h>

[xxgamexx]

struct stat fileStat;
if(stat("example",&fileStat)==0){
//将文件状态返回到结构fileStat中
cout << fileStat.st_size ;

}else{

};

然后对fileStat结构进行比较！！


The structure stat contains at least the following members:


dev_t st_dev ID of device containing file
ino_t st_ino file serial number
mode_t st_mode mode of file (see below)
nlink_t st_nlink number of links to the file
uid_t st_uid user ID of file
gid_t st_gid group ID of file
dev_t st_rdev device ID (if file is character or block special)
off_t st_size file size in bytes (if file is a regular file)
time_t st_atime time of last access
time_t st_mtime time of last data modification
time_t st_ctime time of last status change
blksize_t st_blksize a filesystem-specific preferred I/O block size for
this object. In some filesystem types, this may
vary from file to file
blkcnt_t st_blocks number of blocks allocated for this object

有稍微简单的吗？

编写与系统无关的程序，测试两个文件是否相同的程序哦，还是很感谢大家啊！

vc下可以用 WIN32_FIND_DATA
纯C++的 俺不知道

[Enna]

可以用vc的
