( POD )freeing memory : is delete[] equal to delete ?

当我学C++时，那已经是很久以前的事了。我被告知永远不要使用 delete但是delete[]执行delete[]在单个对象上将相当于 delete 。我知道不要太相信老师，我想知道，这是真的吗？

是否有理由调用 delete而不是delete[] ？

我扫描了SO中可能相关的问题，但没有找到任何明确的答案。

Answer 1

来自标准(5.3.5/2):

In the first alternative (delete object), the value of the operand of delete shall be a pointer to a non-array object or a pointer to a sub-object (1.8) representing a base class of such an object (clause 10). If not, the behavior is undefined.

In the second alternative (delete array), the value of the operand of delete shall be the pointer value which resulted from a previous array new-expression. If not, the behavior is undefined.

所以不:它们绝不等同!
