delete vs delete[] operators in C++(C++ 中的 delete 与 delete[] 运算符)
本文介绍了C++ 中的 delete 与 delete[] 运算符的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

C++中delete和delete[]运算符的区别是什么?

解决方案

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.

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++?

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.
