标题: 请教c++高手。调试的内存问题
我写了个学生管理的，可以插入，删除，查看。我调试时，它没有找到错误。但当我添加了一个学生资料后，再查看全部或者删除这位学生的资料时就说内存出错，请教一下各位c++高手该如何修改。代码如下：
#include <iostream>
#include <string>
using namespace std;
class roll
{
private:                   //学生会成员属性
long int _id;             // 学号
string _name;       //姓名
string _sex;          //性别
string _brithday;    //出生日期
string _look;       //政治面貌
long int _num;             //联系电话方式
string _address;       //家庭住址

public:
roll(long int id,string name,string sex,string brithday,string look,long int num,string address)  //构造函数
{
      _id=id;_name=name;_sex=sex;_brithday=brithday;_look=look;_num=num;_address=address;

}
long int Id() {return this->_id; }
string Name() {return this->_name;}
string Sex() {return this->_sex;}
string Brithday() {return this->_brithday; }
string Look()  {return this->_look;}
long int  Num(){return this->_num;}
string Address() {return this->_address;}

};
int main()
{
roll *member[50];
member[0]=new roll(1234567,"王1","男","11/14/1987","共青团员",36901234,"广东广州");
member[1]=new roll(2345678,"王2","女","12/14/1987","党员",36902345,"广东佛山");
member[2]=new roll(3456789,"王3","男","1/14/1987","共青团员",36903456,"广东深圳");
member[3]=new roll(4567890,"王4","女","2/14/1987","党员",369045678,"广东东莞");
member[4]=new roll(5678901,"王5","男","3/14/1987","共青团员",36905678,"广东中山");
int n=1;
int m=3;
while(n!=0)
{
      cout < <"请选择你要进行的操作：" < <endl;  //选择你要进行的操作
      cout < <"插入学生的基本信息请选择-1" < <endl;
      cout < <"删除学生的基本信息请选择-2" < <endl;
      cout < <"输出基本信息数据项请选择-3" < <endl;

      cout < <"退出请选择-0" < <endl;
      cin>>n;
      m++;
      switch (n)
      {
case 1:
{  string nname;
      string ssex;
      string bbrithday;
      string llook;
      long int nnum,iid;
      string aaddress;
         cout < <"输入学号:" < <endl;
         cin>>iid;
         cout < <"输入姓名:" < <endl;
         cin>>nname;
         cout < <"输入性别:" < <endl;
         cin>>ssex;
         cout < <"输入出生日期:" < <endl;
         cin>>bbrithday;
         cout < <"输入政治面貌:" < <endl;
         cin>>llook;
         cout < <"输入联系电话方式:" < <endl;
