C++ 中的 delete 与 delete[] 运算符

delete vs delete[] operators in C++(C++ 中的 delete 与 delete[] 运算符)

问题描述

C++中delete和delete[]运算符的区别是什么?

delete 操作符释放内存并为使用 new 创建的单个对象调用析构函数.>

delete [] 操作符释放内存并为使用 new [] 创建的对象数组调用析构函数.

在new [] 返回的指针上使用delete 或在new 返回的指针上使用delete []> 导致未定义的行为.

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

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.
