是C ++中删除操作符所需的正确类型吗？ [英] Is the correct type required for the delete operator in C++?

问题描述

void * intptr = new int;
delete (int *) intptr;

是（int *）需要吗？

推荐答案

是的。

是新的。唯一不需要匹配的时间是通过基本指针删除派生类型，其中基本类型有一个虚拟析构函数。

The type must match that which was new'd. The only time it doesn't have to match is deletion of a derived type through a base pointer, where the base type has a virtual destructor.
