learn assembly programming

First talk about some of your own understanding: from a high-level language of the basic say In high-level languages, we sometimes initialize the property settings for a segment of storage space, such as the initial access to the storage space is int, each time the IP = Ip+4, and now want to access in bytes (char), then you need to force type conversion, but this conversion is only useful for a single operation. int A[10] Char *p = (char*) A; If you need time later, you need to convert again.

The results returned when only the first three operations are written and run are the same. Shows the data in the memory area when no operation is performed. The data in the corresponding memory area after two single-step operations is the same as the original value. Ax, the IP value is the same as the value in memo

First of all, thank you for the article written in the beginning of yesterday's comments, everyone's views are different, I hope we discuss more, and common progress. Now I am a daily program to deal with, every day from think of a function how to achieve, how to improve the performance of the program. Sometimes programming this thing is hard to understand, only you experience, you can feel, you do not experience, will never experience!I now wan

The computer course of NetEase Cloud class opens up the course of programming language in the same time. Python, C language, Java, is to choose a study or all learn? Will it be easy to confuse three of them at the same time? Reply content:The main question is a very magical one. I am waiting for the older generation of non-net-class programmers to miss this problem, because in the entry of a language to hav

I am a sophomore majoring in computer science. It is found that learning programming well involves a series of knowledge. For example, to learn the php language well, you must learn Linux well (it must be free, open-source, and mostly developed in this environment in China) mysql, apache, algorithms, some network technologies and protocols, js, html, and cssdiv.

algorithm design. Preferably outside China. Then you will soon be able to become a good programmer. After rigorous training, your thinking ability and feeling about code will be improved quickly. A strong theoretical foundation can make your development better. Learn more about the operating system and read some books on network. Then you will be able to quickly master the programming in this area. 8. The

The first basic concept of Win32 Assembler Win32 programs run in protected mode. In Windows, every Win32 application is put into a separate virtual address space to run. That is to say, each application has a 4 GB address space independent from each other, the operating system converts the 4 GB virtual address and physical memory address when the application is running, and divides the code into data in 16-bit windows, code and other segments have different memory modes. Win32 only has one memor

service program), one BIOS, one DOS, and the use of interrupt mode (INT) for execution. Higher DOS level, priority should be used. The second is the BIOS (write ROM, which is part of the hardware), and finally the peripheral calling program. 80x86 instruction system and addressing method One address (INC, DEC), two addresses (majority), three address directives (few, such as SHL). Operation code as long as the unique binary code can be determined, but in order to facilitate the

Assembly Language Programming Example one of these chapters, we have to bring together the knowledge we have learned. Specifically, let's write a program that uses ODBC APIs. For simplicity, I use Microsoft's Access database (Microsoft Access 97) in this program. Note: If you are using a windows.inc of 1.18 and the following version, you should modify one of the minor bugs before you begin compiling. Looki

The article at the beginning of the list of so many contact, it will inevitably make you feel a bit of ad's meaning, but can not be questioned, there is really so little performance to ^_^, although sometimes too meticulous will be said mother, but fortunately this meticulous for programming, or pretty good!

Now self-taught to complete the C language (feeling and can not do anything), and later with a semester time to learn the C + + grammar (console write), peacetime will also practice a lot of small gadgets, such as mathematical analysis, socket Network application server/client or something.

these languages can be used to get started: Scheme C Java Python Javascript So in contrast, what languages do I not recommend to get started? Shell PowerShell Awk Perl Php Basic Go In general, you should not use the so-called " scripting language " as a starting language, especially for scripting language tools that originate from early Unix systems. Although PowerShell has progressed more than the Unix Shell, it still does not

It's been a long time thinking about which programming language programmers should learn first, what programming languages they must master, and how to learn a sequence. Just to see Mr Kim is also studying the first programming language selected who (http://blog.csdn.net/bit

Recently, in the communication group often have the bitter force small white ask how to learn programming, interested in programming, but do not know, this is a huge to let the big God "speechless" proposition. In the knowledge, csdn and other forums, many peers have also discussed this kind of problem, small series on which the approval of the higher answer to t
