在main函数if(choice1==1)中少了"}"
237~260行

当然,改了之后还是有一堆问题

关于信息修改,我将文件指针移动到修改的地方,用输入的其他信息替换,之后重新输入,为什么不对?
D:\桌面文件\桌面\Debug\CANTING.CPP(421) : error C2664: 'fprintf' : cannot convert parameter 1 from 'char [17]' to 'struct _iobuf *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
提示信息是这样的
