大家可以看到在我加了断点后，运行到clearList的下一行，list里面依旧有首元素（我第一个元素输入的是9）

贴出源程序：

void myList::clearList()

{ 

m_iLength = 0;

/*delete []m_pList;

m_pList = NULL;*/

}

bool myList::listInsert(int i,int*e)

{

if(i > m_iLength)

return false;

else

{

for(int j = m_iLength-1;j >= i;j--)

{

m_pList[j+1] = m_pList[j];

/*m_pList[i] = *e;

m_iLength++;

return true;*///不能放在此处，否则在最开始时无法插入值

}

}

m_pList[i] = *e;

m_iLength++;

return true;

}

cpp文件：

#include"myList.h"

#include<stdlib.h>

#include<iostream>

using namespace std;

int main()

{

myList list1(20);

list1.listTraverse();

int e1 =9;

int e2 =7;

int e3 =6;

int e4 =5;

int e5 =4;

int e6 =1;

int e7 =2;

  list1.listInsert(0,&e1);

//list1.listTraverse();

list1.listInsert(1,&e2);

list1.listInsert(2,&e3);

list1.listInsert(3,&e4);

list1.listInsert(4,&e5);

list1.listInsert(5,&e6);

list1.listInsert(6,&e7);

list1.listTraverse();

cout << endl;

cout << "链表长度：" << list1.listLength() << endl;

list1.clearList();//并没有达到清空list的作用

list1.test();

/*list1.listTraverse();

cout << endl;

cout << "链表长度：" << list1.listLength() << endl;

int ele = 0;

list1.getEterm(3,&ele);

int temp = 5;

list1.locateEterm(&temp);

int curre = 4;

int prior = 0;

list1.priorEterm(&curre,&prior);

int lator = 0;

list1.latorEterm(&curre,&lator);

int i =3;

int deleeterm = 0;

list1.listDeleteElterm(i,&deleeterm);

list1.listTraverse();

cout << endl;

cout << "被删除的元素是：" << deleeterm << endl;*/

system("pause");

return 0;

}
