首先要知道C/C++程序内存区域的划分: 图片来源:https://manybutfinite.com/post/anatomy-of-a-program-in-memory/ 【注意】 栈:从高地址往低地址增长,存放的是非静态局部变量、函数参数以及返回值等具有临时性的值;动态内存的维护都是要用指针保存地址的,栈就是保存指针的地方,因此栈的容量很小,比如VS编译器给...
I've tried generalizing this with templates, but I've been confused by how I should organize the collection of vectors for each component. I had it setup so that they were all in an unordered_map, but how to get the templated functions to find the right map slot to use based simply ...
