一行打印一个单词核心代码

/*state代表是否在单词中的状态*/

while((c = getchar()) != EOF){if(c == ' ' || c == '\n' || c == '\t'){if(state == IN)                //finish the wordputchar('\n');state = OUT;}else if(state == OUT)                 {state = IN;                  //beginning of wordputchar(c);}else                                //inside a wordputchar(c);}
