I certainly don't want to assume they're always going to type a three-letter or a four-letter or a two-letter word I want some dynamism but that's fine because get string can get a string of any length, I can then use the string length function to just ask while the program is running how big is the string that I was handed?

当然我不能假设他总是,输入3个字符或4个字符,或2个字符的单词，我想要动态地分配,因为GetString可以获得任意长度的字符串，然后我可以使用strlen函数,来得到那个我传递的字符串,有多长？
