文件管理程序C++

好的，你可以尝试以下的文件管理程序C++代码：

#include <iostream>
#include <fstream>
#include <string>
#include <dirent.h>
#include <sys/stat.h>
#include <unistd.h>
using namespace std;

                cout << ent->d_name << endl;
            }
        }
        closedir(dir);
    } else {

}

    }
}

}

这个文件管理程序可以列出指定目录下的所有文件、创建文件、删除文件、重命名文件、复制文件、移动文件和获取文件信息。你可以根据需要进行修改和扩展。
