Here's a youtube link to explain myself on what errors I'm getting.
我不明白为什么＆＃34; fstream＆＃34;对象无法正常工作。我声明它，然后我尝试用参数中的完整路径目录打开文件。 https://www.youtube.com/watch?v=mNm_OwVLR5g

I'm posting this answer for those who might one day come across the same problem I did. 
The error was not with the code, other than the missing ";" which user657267 pointed out.

在CS50上咨询另一个社区Facebook后，我发现在终端窗口中使用clang进行编译时，程序编译并运行无错误。我试着仔细阅读堆栈溢出的Q＆amp; A，查看发布好问题的指南，以及help center关于询问的问题。在那里，我发现允许的主题包括程序员常用的software tools。

在这种情况下，我发现Xcode对我来说是 buggy 。我不确定是什么类型的bug。但Facebook集团对二元等的讨论远远超出了我的想法。

我现在要问另一个问题....

我不喜欢绝对的说话，但是每个人都会这样说

IDE 集成开发者环境（面向未来的googlers）

几年后，我在职业生涯中遇到过马车？最好的方法是避免遇到这样的错误，这会给我几小时的BS来从命令行编写代码吗？如果这是一个意见或主观问题，我很抱歉，但有什么其他方式可以提出这个问题。我正在学习如何编写程序，并且我花费时间的最突出的方法之一就是我遇到的调试问题，因为我的IDE编程方式。编译器如何写二进制文件，IDE默认保存它所写的文件等等。
