C++中指针乱了！如何解决

   1: // TestArrayPtr.cpp : Defines the entry point for the console application.

   2: //

   3:  

   4: #include "stdafx.h"

   5: #include <stdio.h>

   6: #include <iostream>

   7: using namespace std;

   8:  

   9: int _tmain(int argc, _TCHAR* argv[])

  10: {

  11:  

  12:  

  13: int* p_Jtobus = new int[6];

  14:  

  15:   for (    int i=0;i<6;i++)

  16:   {

  17:  

  18:       p_Jtobus[i]=i;

  19:     

  20:   }

  21:    cout<<"小段程序一"<<endl; 

  22:    for (    int i=0;i<6;i++)

  23:   {

  24:       int s=  * p_Jtobus;

  25:     p_Jtobus++;

  26:  

  27:         cout<<"out putA"<<i<<"输出的值是"<<s<<endl; //iostream

  28:  

  29:   }

  30:    cout<<"小段程序二"<<endl; 

  31:   for (    int i=0;i<6;i++)

  32:   {

  33:       int s=  * p_Jtobus;

  34:       p_Jtobus++;

  35:  

  36:       cout<<"out putB"<<i<<"输出的值是"<<s<<endl; //iostream

  37:  

  38:   }

  39:  

  40:     char filename[30];

  41:     scanf("%s", filename);

  42:  

  43:     return 0;

  44: }

指针乱啦
第一次 和第二次

如何让他恢复到以前

各位看官如何解决呢！

期待你的静态答案！

第二个for之前
没有把p_Jtobus重置为原来的值
