临时变量没有定义,定义上不就OK啦

(34) : error C2065: 'p' : undeclared identifier
以上错误表示，第34行中p未定义

[面包大师]

(44) : error C2065: 'm' : undeclared identifier
类似的第44行中m未定义

[面包大师]

(35) : error C2227: left of '->data' must point to class/struct/union
(36) : error C2227: left of '->next' must point to class/struct/union
改了未定义这个错误之后，相应的上边的错误也会没有了
