为什么＆QUOT;删除[] [] ... multiDimensionalArray;＆QUOT;运营商在C ++中不存在 [英] Why "delete [][]... multiDimensionalArray;" operator in C++ does not exist

问题描述

我总是想知道是否有在标准C ++语言中删除多维数组运算符。

I was always wondering if there is operator for deleting multi dimensional arrays in the standard C++ language.

如果我们创建一个指向一个单一维数组

If we have created a pointer to a single dimensional array

int *array = new int[size];

删除如下：

delete [] array;

这是伟大的。但是，如果我们有两个二维数组，我们不能做。

That's great. But if we have two dimension array, we can not do

delete [][] twoDimenstionalArray;

相反，我们应该循环并删除项，如这个例子。

任何人都可以解释，为什么？

Can anybody explain why?

推荐答案

从技术上讲，有在C不是二维数组++。什么您使用作为二维阵列是一维阵列，每个元件是一维阵列。因为它不存在技术上，C ++无法删除它。

Technically, there aren't two dimensional arrays in C++. What you're using as a two dimensional array is a one dimensional array with each element being a one dimensional array. Since it doesn't technically exist, C++ can't delete it.
