c++从父目录获取目录路径、解析文件夹名、打印文件内容

#include <iostream>
#include <filesystem>

int main() {
    std::filesystem::path currentPath = std::filesystem::current_path(); // 获取当前路径
    std::filesystem::path parentPath = currentPath.parent_path(); // 获取父目录路径

    std::cout << "父目录路径: " << parentPath << std::endl;

    return 0;
}

#include <iostream>
#include <filesystem>

int main() {
    std::filesystem::path currentPath = std::filesystem::current_path(); // 获取当前路径
    std::string folderName = currentPath.filename().string(); // 获取最后一个文件夹名

    std::cout << "文件夹名: " << folderName << std::endl;

    return 0;
}

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::ifstream file("文件路径"); // 替换为实际的文件路径
    std::string line;

    if (file.is_open()) {
        while (std::getline(file, line)) {
            std::cout << line << std::endl; // 打印每一行内容
        }
        file.close();
    } else {
        std::cout << "无法打开文件" << std::endl;
    }

    return 0;
}
