基本功能均已实现,东西挺多的就不附测试结果了。因为编写数据也挺麻烦的,仓库中每类人员各编写了五个,直接把txt中的数据粘贴到运行窗口
上面代码放的是正确的,在此之前有另外一个版本,在每次读取完文件退出主程序时,跳转xutility发生读写权限冲突,因为string对象维护的是一段内存,而读入二进制文件保存的是内存地址,在下一次读取时这段内存地址发生变化,所以出现错误。解决办法,将四个人员类中的变量定义为char类型的数组。仓库也保存了一份string编写的源码,想看错误可以直接下上跑一下
参考:C++类对象进行文件读取后出现的xutility错误
解决string类型读写问题后,代码没有报错但是一旦运行检索类的功能,出现变量堆栈损坏,首先考虑的是数组中输入的字符超过了定义的长度,所以各个char类型长度要合理定义,查了一下果然是这个问题
参考:有关Run-Time Check Failure #2 - Stack around the variable ‘XXX’ was corrupted.错误的解决方法
