delete不了是因为你访问越界了吧
char *Stack = new char[1]; //动态数组，栈
char **rtSck = new char*[1]; //动态数组，返回栈
所谓动态，没见你怎么动。 不会写就用vector吧，既然是C++就得有C++的写法
delete二维数组需要delete行和列。请看下面的代码：
for(i=1;i<=100003;i++)
{
delete[]nStr[i];
nStr[i]=NULL;
}
delete []nStr;
nStr=NULL;
new和delete是对应的一组内存操作函数，释放内存应该要
delete[]nStr;
delete[]Stack;
delete[]rtSck ;
delete []nStr
