int *data;
data=new int[100];
delete data;
以上程序在Visual C++ 6.0中是正确的，然而在最新的ANSI/ISO C++标准中，它却是错误的。
在以往的日子里，我也一直这么写。昨日在使用CodeGuard除错，发现在delete data一行时报告资源类型不匹配。一查CodeGuard报告，提示使用new []形式创建的资源要使用delete []释放。所以正确的程序应该如下：
int *data;
data=new int[100];
delete[] data;
以上的程序在 Borland C++ Builder 6 中测试通过，CodeGuard对未修改的错误程序报告如下：
