仅使用头文件启动新项目

标签: c++ visual-studio c++-cli

我正在上C ++课,并获得了我的第一个项目。在课堂上,教授只讨论语法,语法等。他从不谈论如何使用Visual Studio。他通过电子邮件向我们发送了一个没有任何解释的头文件,并希望我们将它用于该项目。我不太清楚如何开始使用这个文件。我尝试创建一个空的Visual C ++项目,添加此文件并运行它,但是其中一个,到处都有红色下划线错误和两个,VS说它无法找到可执行文件。如果有人可以帮助我设置VS和/或我的项目,我可以负责制作程序(刚刚完成用Java编写相同的程序)。

这是他发给我们的头文件。从它的外观来看,他有点草率。

... Ughh编译...总之...

如果你打开VS,然后转到文件,你会找到新的项目选项。我假设这是一个Windows窗体应用程序。因此,选择新项目,在语言下选择C ++,然后选择Windows Form App。如果设置完毕,请转到file-&gt;保存所有内容并将其放在目录中。现在拿走教授给你的文件,并将其与该目录中的其余代码文件一起放入。返回项目,在解决方案资源管理器下,右键单击标题文件,添加,添加现有文件,然后选择标题。这应该足以让你开始了!
