So it turns out a really nice shortcut on most systems, oops, is to say if you have a file called hello.c and you wanna turn it into a program called hello, well, make hello just write in the command makeHello and it will do all of that for you automatically and hand you a program called hello.

就是寻找一种能在大多数系统上运行的更快捷的方式，哇！,也就是说，你有一个hello，c的文件,你想把它变成一个名为hello的程序，那么只需要敲入命令,它就会自动为你生成,一个hello程序。
