has always been the understanding of this problem is more hazy, I believe many friends are also like this, always hear the memory will be allocated on the stack, and then in the heap allocation, then what is the difference between them? To illustrate this issue, let's take a look at the organization inside the memory.
When we understand some of the fundamentals of the. NET framework, it is really necessary to understand some of the underlying knowledge. For example, how the. NET Framework is memory-managed, how it is garbage collected ... In this way, we can write more high-performance programs. In the. NET Framework, there are 2 places for us to save management data: One is "heap", also called "Managed

. Before we dive in, let's take a look at the "Object life cycle"The life cycle of an objectWhen we create an object with the New keyword, the object is assigned to the CRL managed heap. This managed heap is in memory. And this allocation of object space is very fast, because each time in the last side of the managed

I. Basic Memory StructureThe programmable memory can basically be divided into the static storage area, heap area, and stack area. Their functions are different, so they are used differently.Static storage zone: it is allocated when the program is compiled, and the existing program exists throughout the runtime. It stores static data, global data, and constants.S

How can I dynamically apply for a two-dimensional array?1. What is a stack? 1. Memory Allocation The memory occupied by a C/C ++ compiled program is divided into the following parts:1. STACK: the st
NOTE: Stack is automatically allocated by the system, which is faster. But programmers cannot control it. Heap is the space that programmers apply for as needed. Generally, the speed is slow and memory fragments are easily generated. Is a typical C memory distribution chart in APUE: BSS segment(Bss segment) is usually a mem
First, Memory layout1, Stack: The compiler automatically allocates the release, storing the function parameter value, local variable value, etc., its operation method is similar to the stack in the data structure.2, heap area (heap): Generally by the programmer allocation release, and the data structure in the
