有什么简单的方法可以找到当前的工作目录吗？c++

#include <unistd.h>
#include <iostream>

int main() {
    char path[FILENAME_MAX];
    if (getcwd(path, sizeof(path)) != nullptr) {
        std::cout << "Current working directory: " << path << std::endl;
    } else {
        std::cerr << "Failed to get current working directory." << std::endl;
    }
    return 0;
}

#include <iostream>
#include <filesystem>

int main() {
    std::filesystem::path path = std::filesystem::current_path();
    std::cout << "Current working directory: " << path << std::endl;
    return 0;
}
