定义于头文件<filesystem> classdirectory_iterator; (C++17 起) directory_iterator是一个迭代于目录的directory_entry元素上的遗留输入迭代器(LegacyInputIterator)(但不造访子目录)。迭代顺序是未指定的,除了每个目录条目只被造访一次。跳过特殊路径名dot和dot-dot。 若前移
#include <iostream> #include <string> #include <filesystem> using namespace std; using namespace filesystem; int main(int argc, char** argv) { for (auto& entry:recursive_directory_iterator(argv[1])) { bool isNormalFile = is_regual_file(entry); if (isNormalFile) { const string pathSt...
2) 尾迭代器(默认构造的 recursive_directory_iterator) 示例 运行此代码 #include <fstream> #include <iostream> #include <filesystem> namespace fs = std::filesystem; int main() { fs::create_directories("sandbox/a/b"); std::ofstream("sandbox/file1.txt"); fs::create_symlink("a", "sandbo...
预期答案: C++17引入了std::filesystem库,它提供了一套全面的文件系统操作API。这些操作包括文件的创建、删除、查询、路径操作、目录遍历等。主要的类和函数有:path、directory_entry、directory_iterator、recursive_directory_iterator、create_directory、remove、rename、exists、file_size等。 问题11: 请描述C++17中的...
miniz_cpp::zip_file file; const std::string base_path = "./test/"; for (const auto& entry : std::filesystem::recursive_directory_iterator{ base_path }) { auto path = entry.path().string(); auto zip_path = normalize_path(path, base_path); if (entry.is_directory()) { // 如...
1.先mark一个文件操作:遍历(或者迭代遍历)指定目录,boost::filesystem可真好用 1for(const auto& it : boost::filesystem::directory_iterator("/your/path")) {2if(it.path().extension() ==".pcd") {3std::cout << it.path() <<","<< it.path().filename() <<","<< it.path().stem...
#include "pch.h" import std.filesystem; import std.core; int main(int argc, char* argv[]) { ::std::experimental::filesystem::path directory("example"); ::std::experimental::filesystem::recursive_directory_iterator iterator(directory); } ...
例如,这是 Windows 上Boost.Filesystem库的调试 DLL:boost_filesystem-vc100-mt-gd-1_57.dll。文件名中的标记讲述了完整的故事。这个 DLL 是使用 Visual C++ 10.0 编译器(-vc100)构建的,是线程安全的(-mt),是一个调试 DLL(d),动态链接到调试版本的运行时(g)。Boost 的版本是 1.57(1_57)。 系统布局 ...
The std::filesystem::create_directory 2-parameter version was changed to call the 1-parameter version, as the underlying CreateDirectoryExW function would use copy_symlink when the existing_p was a symlink. std::filesystem::directory_iterator no longer fails when a broken symlink is found. std...
