我知道创建文件的方法有很多，但是我对文件系统库很感兴趣.

推荐答案

此代码将创建一个文件夹和一个txt文件(+在其中添加一些文本)

This code will create a folder and a txt file (+ adds some text into there)

#include <iostream>
#include <filesystem>
#include <fstream>

int main()
{
    std::filesystem::path path{ "C:\\TestingFolder" }; //creates TestingFolder object on C:
    path /= "my new file.txt"; //put something into there
    std::filesystem::create_directories(path.parent_path()); //add directories based on the object path (without this line it will not work)

    std::ofstream ofs(path);
    ofs << "this is some text in the new file\n"; 
    ofs.close();

    return 0;
}
