相关疑难解决方法(0)

我正在使用 Codeblocks 17.12 并且已经将编译器设置设置为 C++11 标准。我正在学习 Bjarne Stroustrup 的书“编程 - 使用 C++ 的原则和实践”。在他的书中，他要求包括“std_lib_facilities.h”。我从他的网站复制它并保存在“Mingw”文件夹的“include”文件夹中。之后，我开始制作一个简单的程序：

#include<iostream>
#include "std_lib_facilities.h"
main()
{
    std::cout<<"Hello world";
}

但是编译器显示以下错误和警告：

 warning: This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.  
 Please use a non-deprecated interface with equivalent functionality instead. 
 For a listing of replacement headers and interfaces, consult the file backward_warning.h. To disable this warning use -Wno-deprecated. [-Wcpp]

我在Stroustrup网站上包含了std_lib。我的代码是：

#include "c:\Users\theresmineusername\Documents\Visual Studio 2017\std_lib_facilities.h"

int main()
{
    cout << "Hello, World!\n";
    return 0;
}

所以我有两个错误：
