使用new int [10]分配的内存必须使用delete []解除分配。

谢谢你们:)
我认为Wilson，Paul，Tim等都是对的， - - ...只是

Thank you guys :) I think Wilson, Paul, Tim etc. are right, the statement omit some words therefore confused me - -...it's simply

delete [] p; 

我从来没有见过Rob的回答，看起来真的很新！任何解释将不胜感激。）

I've never seen Rob's answer though, looks really new to me! Any explanation will be appreciated.:)

delete[] new int[10];

推荐答案

您缺少一个变量来保存返回的值从新。您应该有：

You're missing a variable to hold the value returned from new. You should have something like:

int* intArray = new int[10];

然后当您要删除内存时，可以通过变量引用它：

then later when you want to delete the memory, you reference it through the variable:

delete[] intArray;
