ME:: L, vector变量是存放在堆上还是栈上的?网上说法不一,我也没有找到权威的表述

L: 堆、栈 和vector有啥关系?

L: 你把它放哪里,它就在哪里

ME: [分享]堆、栈的地址高低? 栈的增长方向? https://www.zhihu.com/question/36103513?sort=created

ME: 这个例子作者认为vector在堆上.

L: vector管理的内存在堆上

L: vector对象本身在栈上

L: 你把它放哪里,它就在哪里

ME: 那他的a3[1]还是在堆上吗

L: 在

ME: 那a3是在栈上吧?

L: 在栈上定义的对象,就在栈上

ME: OK


不知哪里来的说法:

无论你的定义是:

vector<int*> *p = new vector<int*>;

还是

vector<int*> p;

其元素都是在堆上进行分配。


别的论述:

​https://www.it1352.com/454497.html​

vector<Type> vect;

will allocate the vector, i.e. the header info, on the stack, but the elements on the free store ("heap").

vector<Type> *vect = new vector<Type>;

allocates everything on the free store.

vector<Type*> vect;

will allocate the vector on the stack and a bunch of pointers on the free store, but where these point is determined by how you use them (you could point element 0 to the free store and element 1 to the stack, say).
