从向量取消分配堆内存. [英] Deallocating heap memory from a vector.

问题描述

我有一个向量，其中存储了结构对象.现在我需要释放内存.
请告诉我如何?

I have a vector in which I stored objects of structures. Now I need to deallocate the memory .
Kindly tell me how?

推荐答案

使用 ^ ]方法.

内存将由矢量析构函数释放(除非您在矢量中存储了指针).
如果向量仅包含指向对象的指针(因为您告诉我们对象是堆分配的)，则必须delete每个指针(对向量项进行循环).

Memory will be released by vector destructor (unless you have stored pointers inside the vector).
If your vector contains just pointers to the objects (since your are telling us the objects are heap allocated) then you have to delete every pointer (make a loop on vector items).
