Ask for help from someone who is proficient in C 20

Send it out to see how to add it to you if you don't send it out!!

Summary. Hello, many people will say that they are proficient in the C language, probably because they have a lot of experience and skills in the C language, are able to write C programs proficiently, handle various data types and algorithms, and are able to solve various problems. In addition, C is a programming language that is widely used in the field of computer science, and many people learn C when they study computer science, so they often use C language to write programs.

However, being proficient in C is not an easy task. C has a lot of detail and complexity, and it takes a lot of time and effort to learn and understand. In addition to basic syntax and semantics, you also need to understand advanced concepts such as compilation and linking processes, memory management, pointers, and arrays in C.

Therefore, for those who are really proficient in the C language, they need to have high programming ability and experience to be able to apply the C language to solve various problems in real projects.

So why doesn't anyone dare to claim to be proficient in object orientation?

Object-oriented is a programming paradigm that emphasizes the idea of designing a program as an interaction of a set of objects. To be proficient in object orientation, you need to have a deep understanding of object-oriented concepts, principles, design patterns, etc., and be able to skillfully use and use the language and tools for sensitive objects. However, many people may not have a deep enough understanding of object-orientation, or they may not fully use object-oriented ideas and techniques in actual programming, so they dare not claim to be proficient in object-orientation.

In addition, object-oriented programming is a programming paradigm that is constantly evolving and evolving, and with the emergence of new technologies and ideas, the concept and practice of object-orientation are constantly changing. As a result, even experts who are well-versed in object orientation may need to constantly learn and update their knowledge. Object-oriented programming is a complex science, and mastering object-orientation requires continuous learning and practice, and it takes enough self-confidence and humility to say that you are proficient in object-orientation.

Summary. Many people mark themselves proficient in C on their resumes or social **, which may be due to the following reasons:1

C is a widely used programming language, and programs written in C contain a large number of applications in many fields and industries, such as operating systems, compilers, database management systems, game development, and more. 2.C is a relatively early programming language, and its theoretical foundation is relatively simple, easy to understand and learn, so many programmers have learned basic C programming knowledge.

However, proficiency in C requires in-depth programming experience and skills, as well as knowledge of various advanced features, library functions, and more. Therefore, if you claim to be proficient in C language in an interview or job, you need to be prepared to face more specific and in-depth questions to demonstrate your C language skill level.

So why doesn't anyone dare to claim to be proficient in object orientation?

Object-oriented is an important concept in the computer programming chain, and mastering object-oriented thinking and being able to skillfully use object-oriented programming technology is one of the basic skills of programmers. However, subtle semantic differences and different levels of cognition can lead to a perception of"Proficient in object orientation"The definition is different, so simply saying that you are proficient in object orientation is subjectively biased and may cause some controversy and questioning. In addition, computer programming is a field that is constantly evolving and evolving, and even if you are already proficient in a certain programming technique or concept, you still need to constantly learn and improve in your daily programming practice, so even if you have a lot of experience, you may not dare to say yourself accurately"Proficient"Some kind of technology.

So, even if you have a deep understanding of the subject and years of practice, you should prove your level with humility and practical performance.

Just understand that % is the surplus, for example:

5%2 is to divide 5 by 2 to find its remainder, because 5 2 = 2 remainder 1, so the value of 5%2 is 1

Since the value of a is 5, (a+100)%2 is (5+100)%2=105%2, of course

In fact, the difficulty of this problem is not (A+100)%2, but A 2, in C language, int type divided by int type, the result is also int type, that is, the quotient is directly rounded, a 2 is 5 2, in mathematics 5 2 =, rounded to 2 (note that rounding is not rounded, directly discard the decimal part), that is, 5 2 = 2

The value of the entire expression (a+100)%2+a2 is 3

I will definitely be able to master C++ in half a month. Your C language foundation is good, right? CSDN is recommended

Proficient in C++ language, familiar with C++ syntax, including object-oriented concepts, templates, etc., this stage requires a relatively difficult process, and requires learning a lot of books, including "C++ Programming Language", "Effective C++", "More Effective C++", "Thinking in C++", "C++ Object Model", "C++ Template", if the above books are already very familiar, I think, in the learning stage, which is already very good. The process can be completed at university, it takes one to two years, and it should be purely theoretical, and it can only be considered familiar. In the process, there are some simple procedures that need to be done.

C++ to do projects, use C++ to do projects, you need more other libraries, such as UI libraries, you also need to use some network libraries, etc., at this time, you can see the breadth and profundity of C++, at this time, C++ language knowledge is not enough, you need to supplement some platform development knowledge, look at the open source C++ project. For example: Windows programming, C++ network programming, DirectX game development, if you have done more than two projects in C++, that's very good.

The highest level is mastery, and nature is the accumulation of quantity to have a change in texture.

C is the basis for programming jobs such as programmers in the future! You need to understand all the knowledge points in it, so as not to suffer in the future!

C is just the basics, you need to learn the functions and pointers, as well as the structs. The future is important, especially when learning about data structures.

The important thing is to practice on your own computer. That's how I am, not bad.
