首先，你应该自己动手写一遍，如果你有困难，可以找我们寻求帮助。这不会太难，简单的循环，检查字符是否为空，导致循环退出，还有一两件小事应该变得明显。从练习中复制比粘贴别人的代码。

You should have a go at writing it yourself to begin with, and if you have trouble get back to us for help.
It really wont be that hard, a simple loop, a check if the character is NULL which causes the loop to exit, and one or two more little things which should become apparent.
You will learn far more from that exercise than copy/pasting someone elses code.
