dream come true !(2)

count_word:
思想：用一個變量標志單詞的開始和結束，也就是說 what i do is to judge where the word begin and where the word end
notes: maybe the interviewer didnot give enough information deliberately,they want me to check this detail,so i should communication with him to check the definition of word.

int ?count_word( char ? * s)
{
?? if ( null ? == ?s)
????? return ? 0 ;
??? int ?count? = ? 0 ;
??? int ?i? = ? 0 ,flag? = ? 0 ;
??? while (s[i]? != ? ' \0 ' )
??? {
????? if (isalpha(s[i])? && ?flag? == ? 0 )
????? {
????????flag? = ? 1 ?; // ?word?begin
????????count? ++ ;
??????}
????? else ? if (flag? == ? 1 )
?????? {
???????? if ( ! isalpha(s[i])? && ?s[i]? != ? ' _ ' )
?????????flag? = ? 0 ;
???????? else ? if (s[i]? == ? ' _ ' )
????????? {
??????????? if ( ! isalpha(s[i + 1 ]))
??????????????flag? = ? 0 ;
?????????} ???
???????}
??????i ++ ;
????}
?? return ?count;
}
