CRT detected that the application wrote to memory after after the end of heap buffer(这个经常忘掉)

在VS2005写完程序后,运行后弹出对话框显示:
HEAP CORRUPTION DETECTED:
CRT detected that the application wrote to memory after after the end of heap buffer
最后定位到代码
ans = new int[size_a+size_b]; // 动态分配数组空间
delete [] ans;
一把delete [] ans;删掉程序就不弹出错误,这是为什么呢??
错误原因:
因为对内存的操作越界了,超出所分配的内存的边界。
解决:
增大分配的内存!
e.g.
ans = new int[size_a+size_b +1 ];
或者加到自己适宜的大小,问题即可解决...
总结:
对内存的操作要细之又细,new完后要delete,操作时不要越界(包括向前越或向后越).......
