vc程序debug不知道为什么？ help me

[aoxue]

有一段代码每次运行都有错误提示，是错在那啊？我估计是new .delete出错了，是不是
要测试new,delete?
但不知道怎么改啊？for example:
#include<iostream>
#include<cstring>

using namespace std;

int main(void) {
const char *pc0 = "this is very long string";
char *pc1 = new char[100];

int lenth = strlen(pc0);
for(int ix = 0; ix < lenth; ix++) {
pc1[ix] = pc0[ix];
pc0++;
pc1++;
cout << "*pc0 = " << *pc0 << endl;
}

cout << "*pc1 = " << *pc1 << endl;

delete [] pc1;
return 0;
}
===============================================================
编译能通过，可运行就出问题了，编译器提示：
Debug Asserting Failed!

Program:c:/Program Files/microsoft Visual Studio/MyProject/stringVersion
/DEBUG/stringVersion.exe (这是我vc的安装路径）
File:dbgheap.c
line:100012

expression:CtrIsValidHeapPointer(pUserData)

pc1已经不是声明时的位置了
char *pc1 = new char[100];改成char *p = pc1;
delete [] pc1;改成delete [] p;

[gufengduyu]

delete [] pc1;这句有问题
pc1现在并没有指向数组的开始位置，delete无法知道pc1数组的边界

应该在程序开始的时候定一个指向数组开头的指针
char *pc1 = new char[100];
char *pHead;//添加指针

pHead = pc1 ；

结尾改为：
delete [] pHead;
