我写的程序出现段错误，求debug哈！回答好还可以再加几百~~
要求是把一句英语的每一个单词，最开始的所有的辅音（aeiou除外所有字母）放到单词为末尾，从元音开始输出，最后再加‘ay’，比如单词love，l是辅音，所以从ove开始打字，ove+l+ay。play这个单词，pl辅音，ay开始，ay+pl+ay。
不管输入过少空格，都变成一个，只考虑最后有一个标点（. ? !）!
例子：
$ ./piglatin
Enter a sentence (up to 80 characters): The quick brown fox jumped over the lazy dog.
Ethay ickquay ownbray oxfay umpedjay overway ethay azylay ogday.
$ ./piglatin
Enter a sentence (up to 80 characters): Do we really need to do this?
Oday eway eallyray eednay otay oday isthay?
$ ./piglatin
Enter a sentence (up to 80 characters): I thought this was a course in engineering computation!
Iway oughthay isthay asway away oursecay inway engineeringway omputationcay!
