問題描述

我希望把一個文本文件里面的內(nèi)容讀出來，但是不知道為什么讀取的那一行存放到自己自定義的struct類型的char *類型中總是把前面的讀取的char *給內(nèi)容給修改掉。出問題的地方我用注釋標(biāo)出來了

你期待的結(jié)果是什么？實(shí)際看到的錯誤信息又是什么？

while循環(huán)中customer.name = strtok(buffer, " ");我期望的結(jié)果是讀取之后queue中customer.name應(yīng)該是s0,s1,s2....s9，s10,但是結(jié)果卻都是s10。為什么struct里面的char *類型的name會這樣？我該怎么改呢？謝謝啦
