C # several layers of language,

C # several layers of language,

I received a letter from a recent C # training student. Although the student lacks skills in the past, he has a strong learning base and is growing fast in the training. Even if you are familiar with the. NET Framework (revision), you are not enough to become a master. The purpose of the letter is to help you in the advanced direction.

To tell the truth, I generally don't want to give guidance on the major issues related to personal development, because too many personal or insightful experiences tell me that life is really hard to predict, kindness, wisdom, and diligence these character we cherish often encounter terrible reality. I feel that when I encourage a person, I only pay attention to "procedural justice" and have little confidence to assure him "Result Justice ". Life is not like software. It can have a good output under a good design.

However, if I do not want to disappoint my post-learning, I will take the liberty to write down the following simple experiences, extract a paragraph, and accept the review from my friends:

Regardless of specific fields (such as search, video, network, etc.), the vertical direction of a single programming language is roughly divided into the following layers.

1. basically use the C # syntax to complete some basic program tasks with the support of various tools and sample code

2. Be familiar with object-oriented and component structures, and be familiar with them to complete the development tasks of small-scale information management software projects.

3. Have a deep understanding of the CLR kernel mechanism and have a clear understanding of the advantages and disadvantages, applicability, and efficiency of various types and. NET platform mechanisms, so as to complete projects with high technical complexity.

4. Be able to easily grasp the loose coupling principle and accurately use various languages to construct large-scale software projects.

5. Be able to understand and grasp programming languages from the perspectives of computer abstraction, system and historical development.

I have determined that you are currently in a position between 2 and 3. Of course, some of your growth in these directions can greatly help you, and some of your training can only help you, experience and attitudes towards technology are even more important

To be honest, the programming language shouldn't be so important, but now, after nearly two years of training experience, Lin Zong, a trainee, has almost no programming experience at the bottom, to the high-end enterprises as key development tasks. It is found that in China, programming languages are actually a hard injury to most developers, and most programmers are between 1-2-the reason is not much to mention, the computer education at Chinese universities is only after a person has a thorough understanding of the computer, can he realize how absurd and failed it is.

It may have been inspired by the passion of Xian, such as Cai Yuanpei and Mei Xiaoqi. Two years ago, he started to go to software training with an education mentality. It was really hard for two years, however, although it is not big, I am very pleased to see that the reality is being changed.

& In C Language

& Can be used as the bitwise AND or address fetch Operator
The following describes two usage methods:
1. bitwise and operation bitwise AND operator "&" are binary operators. Its function is the binary phase corresponding to the two numbers involved in the operation. The result bit is 1 only when the two binary numbers are 1. Otherwise, the result bit is 0. The number of involved operations is supplemented.
For example, 9 & 5 can be written as follows: 00001001 (Binary complement of 9) & 00000101 (Binary complement of 5) 00000001 (Binary complement of 1) Visible 9 & 5 = 1.
Bitwise AND operations are usually used to clear some bits or retain some bits. For example, if a clears the high eight bits of 0 and retains the low eight bits, it can be used as a & 255 operation (255 of the binary number is 0000000011111111 ).
2. Get the address
& As The unary operator, the result is the address of the right operation object.
For example, & x returns the address of x.
The address itself is an abstract concept used to indicate the logical location of an object in the memory.
