delete vs delete []运算符 [英] delete vs delete[] operators in C++

问题描述

C ++中 delete 和 delete [] 之间的区别是什么？

解决方案

delete delete [] 操作符释放内存和调用析构函数用 new [] 创建的对象数组。

使用 delete 在由<$ c $返回的指针上的 new [] 或 c> new 会导致未定义的行为。

What is the difference between delete and delete[] operators in C++?

解决方案

The delete operator deallocates memory and calls the destructor for a single object created with new.

The delete [] operator deallocates memory and calls destructors for an array of objects created with new [].

Using delete on a pointer returned by new [] or delete [] on a pointer returned by new results in undefined behavior.
