ruby memory allocation

First, prepare the knowledge-memory allocation of the program:The memory used by a program compiled by C + + is divided into the following sections:1. Stack (stack)-Automatically allocated by the compiler to release, store the function parameter value, local variable value and so on. It operates in a manner similar to a stack in a data structure.2, heap area (hea

Ah, I started cleaning when I got home from work. It wasn't done until the early morning. It was really tired. However, it is planned that this article must be completed today, so you can't sleep without writing it. Let's get into the subject as soon as possible! We often use functions or operators such as malloc or new to dynamically allocate memory. The memory here refers to heap

Introduction Garbage collection technology is not the Java language Initiative, the 1960 was born at MIT Lisp is the first real use of memory dynamic allocation and garbage collection technology language. Three issues to consider for garbage collection technology are: 1. Which memory needs to be recycled 2. When to recycle 3. How to Recycle The distribution

System blue screen, a large part of the system itself is caused by the code defects, and the system code defects are largely related to improper memory allocation. Understanding memory allocation is necessary for a qualified program, because of problems such as stack overflow, buffer overflow, and so on due to improper

Preface: As an Android programmer, if do not understand C/s development, then Android JNI, NDK, video decoding, audio decoding can not be developed, there is a need for us to learn, come on. Today we start to quickly explain C language, Java based people are suitable to read this blog. -----------Split Line-------- About the C language memory allocation is mainly: 1. Stack area (stack): Windows, stack

First, IntroductionIn the Java technology system mentioned in the final analysis of memory automation management is the allocation and recovery of memory two problems, before and we have talked about the knowledge of Java recycling, today to talk about the Java object in memory all
