粗略扫了一眼,发现结构的运算符错误。

用指针访问结构成员的运算符是 ->
结构变量访问结构成员的运算符是 .

另外,你的程序是到是C还是C++?
如果是C++,那么你发错版面了,友情提示一下。
C的源代码文件后缀是 .c
C++的源代码文件后缀是 .cpp

赞同!    学写代码的第一课是准备运行环境和Helloworld   ,然后在接触变量、循环递归等等一系列概念的时候老师就应该开始有意识地培养“读懂错误信息”的能力了。我是在网上Mooc学的编程,老师就有教怎么看。
然后自己在解决对应报错信息的过程中逐渐熟练。可以说大部分“错误信息”能发现的问题都只是语法上的疏忽。
另外,新手写程序应该一小段一小段地写,一个功能一个功能地调试运行测试。等都写完了才开始改 一方面很多思路都忘了,改起来略费劲;另一方面有些逻辑上的错误一旦需要该结构那代码就得大段大段地删掉,这是及不划算的。养成习惯,以后写几千几万行的代码才不会滚屏滚到你费

回复 5楼 书生牛犊
这并不奇怪,中国大学CS专业最可怕的地方恐怕还不是到现在还在用谭浩强的垃圾书,还在于根本不会教学生如何Debug,而大部分学生也挺奇葩的,竟然就跟着学校的学,自己也不去注意这些东西,对编译器的警告和错误提示视而不见,太可怕了。

另外,知识结构不完整。

我觉得所有的学校在面对新生的时候,都应该从计算机操作和常识开始,然后扩展在硬件常识。

我就遇到过一个挺逗的人,竟然不知道什么是CMD,甚至于怎么打开都不知道。

最重要的一点却是依旧没改。
C的后缀是.c
.cpp是C++的后缀。

*re 的类型是什么?
