本人是C语言新手,现在做作业遇到一个问题,请教各位大大.

如果我输入一段英文的文章,然后用什么方法可以将它按照ABCD...这样的顺序排列出来呢?

比如我输入

I love you, baby. You are my forever.

然后会显示
are               1
baby              1
forever           1
I                 1
love              1
my                1
you               2

后面的数字显示这个单词出现的次数,前面是按照字母排列

请问各位可以给點提示或者帮忙一下嘛?

谢谢楼上的..我自己也寫了一个程序,不知道还需要那些改进.
#include <stdio.h>
