仍然使用c ++ std_lib_facilities.h吗? [英] Is c++ std_lib_facilities.h still used?

问题描述

我正在从Bjarne Stroustrup的《编程:原理与实践》中学习C ++.他们提供了一个示例程序:

I'm learning C++ from Programming : Principles And Practice By Bjarne Stroustrup. They have given a sample program:

// read and write a first name
#include "std_lib_facilities.h"
int main()
{
    cout << "Please enter your first name (followed by 'enter'):\n";
    string first_name; // first_name is a variable of type string
    cin >> first_name; // read characters into first_name
    cout << "Hello, " << first_name << "!\n";
}

当我在Visual Studio中键入相同的代码时，它给头文件"std_lib_facilities.h"提供了错误.我很困惑 这个头文件.

When I type the same code in visual studio, it gives error for the header file "std_lib_facilities.h". I'm confused with this header file.

它还在用吗?除了该标头，我还能使用什么?

Is it still used? What else can I use instead of this header?

推荐答案

在本书的附录(特定于C.3.2)-编程:使用C ++的原理和实践-中，您实际上可以找到作者对此进行解释特定的头文件-std_lib_facilities.h，他留下了供读者下载的链接( http://www.stroustrup.com/Programming/std_lib_facilities.h ).

In the Appendices (C.3.2 to be specific) of the Book - Programming: Principles and Practice Using C++ -, you can actually find the author explaining about this specific header file - std_lib_facilities.h, and he left a link for the readers to download (http://www.stroustrup.com/Programming/std_lib_facilities.h).

由于学习者必须下载该文件并将其放置在您选择的目录中，因此我推断出该文件不是人们实际使用的头文件，而只是用于教学目的.

Since learners must download the file and place it in a directory of your choice, I deduce from this point that the file is not a header file people would actually use, but solely for pedagogical uses.
