一个关于程序设计的问题

各位高手,今日编写了一端程序设计代码. 但在使用时发现总是出现内存不能读的错误 由于本人为初学者,水平有限,希望各位赐教.不胜感激~!
要求:模拟手机通讯录管理系统，实现对手机中的通讯录进行管理，功能 （1）要求：A办公类，B个人类 ，C商务类。 当选中某类时，显示出此类所有数据中的姓名和电话号码。 （2）增加功能：能录入新数据，一个结点包括：姓名，电话号码，分类（办公类，个人类，商务类），电子邮件，类如：杨春 13567772898 商务类 [email]chuny@126.com[/email]。当录入重复的姓名和电话号码，则提示数据录入重复并取消录入，当通讯录中超过15条信息时存储空间已满，不能再录入新数据，录入的数据能按递增的顺序自动进行编号 （3）修改功能：选中某个人的姓名时，可对此人的相应数据进行修改。 （4）删除功能：选中某个人的姓名时，可对此人的相对数据进行删除并自动调整后续条目的编号，

你不至于要别人一行一行看完代码吧。你一点也不能缩小范围吗？

在哪down的源码
改下头文件
再把“< <”全部替换成“<<”就行了

如楼上所说
开头加一个#include <iostream.h>
然后把“< <"改成"<<”就OK了~
