急问:这段程序释放内存时为啥出问题?谢谢
#include <cstring>
#include <iostream>

using std::cout;
using std::endl;

int main()
{
char s[] = "biaobiao;liyan;lijianjun ";
char sep[] = "; ";
char* strPtr[20];
int strCnt = 0;
char * result;

result = strtok(s,sep);
while(result != NULL)
{
strPtr[strCnt] = new char[strlen(result)];
strcpy(strPtr[strCnt], result);
strCnt++;
result = strtok(NULL,sep);
}
for(int i = 0; i < strCnt; i++)
{
cout < <strPtr[i];
}
cout < < endl;
for(i = 0; i < strCnt; i++)
{
delete [] strPtr[i];
}
return 0;
}

[解决办法]
1.
strPtr[strCnt] = new char[strlen(result)];
====>
strPtr[strCnt] = new char[strlen(result)+1];

2.
delete [] strPtr[i];
===>
delete strPtr[i];

[解决办法]
要注意字符串结尾处有一个 '\0 '占用一个额外内存
