Hello World C++错误 - cmath

Question

我是C++的完整初学者。我正在使用fltk 1.3.x的microsoft visual studio 2015，并遵循Bjarne Stroustrup的“Programming Principles and Practice Using C++”。我正在开发的当前程序是Hello World，第52-54页的练习。

我写的代码（/从书复制并用于std_lib_facilities.h [www.stroustrup.com/Programming/include-std_lib_facilities.doc]支撑DOC）是：

//My first hello world program 
#include "../../../std_lib_facilities.h" 
int main() //C++ programs start by executing the function main 
{ 
    cout << "Hello, World!/n"; //output "Hello, world!" 
    keep_window_open();   //wait for a character to be entered 
    return 0; 
} 

然后我去建设 - >编译并发生这种情况...

我在想，这涉及到std_lib_facilities.h文件。本书建议使用fltk 1.1.x和visual studio 2005，所以也许这也是问题的一部分？

你可以给任何见识，非常感谢。

谢谢。

Im相当新的太多，但我的继承人是如何做到使用Visual Studio的那样：

---

// my first program in c++ 

#include <iostream> 

using namespace std; 

int main() 

{ 

cout <<"Hello World! I am a c++ program."; 

    return 0; 
} 

---

基本上所有你需要的是使用的#include <的iostream> 会告诉电脑使用这些功能来执行程序（取出空格）。 您还需要包含：using namespace std;如果你想说“cout”。否则，你必须在cout之前指定并说std。最后你可以拿出“保持窗口开放的东西”。只要你点击CTRL-F5来运行程序，你就不需要那个。 希望帮助！ Goodluck！
