问题描述
[]
所以你看到这里他有3个文件：main.cpp，Sally.h和Sally.cpp，他在Sally.cpp文件中定义了一个void函数，语法为void Sally :: printCrap（）。我很困惑，为什么他要把类的名称用于在类外定义一个函数？有人可以解释一下吗。我真的很感激！
我的尝试：
对于小而不详细的问题很抱歉，但我限于200个字符：XI希望你理解我的问题，并希望你能解释我。
谢谢！

So you see here he has 3 files: main.cpp, Sally.h and Sally.cpp and he is defining a void function in the Sally.cpp file with syntax void Sally::printCrap(). I got confused in that why he is putting the name of the class for defining a function in outside the class ? Can someone explain me that. I will be really thanksful!
What I have tried:
Sorry for the small and not detailed question but I am limited to 200 characters :X I hope you understood my question and hope you will explain me that.
Thanks!
