filesystem

c++遍历目录

#include <iostream>
#include <filesystem>

int main() {
    namespace fs = std::filesystem;

    // 遍历当前目录
    for (const auto& entry : fs::directory_iterator(".")) {
        std::cout << entry.path() << '\n';
    }

    return 0;
}

递归遍历

directory_iterator

#include <iostream>
#include <filesystem>

namespace fs = std::filesystem;

            std::cout << entry.path() << '\n';
            if (entry.is_directory()) {
