【Cherno的C++视频】Stacks vs heap in C++

#include 

// stack is typically an area of memory which has a predefined size, usually around 2 megabyte or so.
// 
// heap is an area that is also kind of predefined to a default value however it can grow as the application goes on.
// 
// the physical location of these 2 areas of memory is ultimately the same, in RAM.
// they work differently but fundamentally what they do is the same.
// the difference is how stack and heap allocate memory for us.
// check out:DEBUG->WINDOW->MEMORY->MEMORY1

struct Vector3
{
	float x, y, z;

	Vector3()
