How can I learn C well, get a Level 2 C certificate and a programmer certificate, and kneel down to

It's not difficult to take the 2nd level test Level 2 is divided into written test and written test You can buy the second-level practice questions and do it Some of them involve data structure and software engineering On the computer, isn't there that CD-ROM, do all the questions inside, have a general understanding, know how to find errors, and the ability to debug **, it's enough. I had been preparing for the exam for a month. If you want to learn better, it is recommended that you watch some c** on the Internet, and there is more hands-on, more typing**, such as the addition, deletion, modification and query of the array.

As for programmers, you can take a look at some of the information I have compiled for you, which may be helpful to you. 1.Programmer Exam Mock Papers – Afternoon Questions.

2.Programmer Exam Mock Papers – Morning Questions.

3.Programming knowledge for programmers.

4.Programmer pre-exam practice questions and answer analysis.

1. The second-level certificate indicates that the holder has basic computer knowledge and basic application ability, can write programs in high-level computer language, and can be engaged in the preparation of computer programs, teaching and training of primary computer computing holes, and business and marketing services related to informatization in non-stupid enterprises.

2. One of the thresholds for applying for civil servants, some regions and some positions.

3. Hospitals, banks, teachers, enterprise technicians and other staff who need to assess their professional titles can be exempted from the corresponding computer examination after work.

1.It is one of the three major certificates (graduation certificate, CET-4 certificate, and computer level 2 certificate) for contemporary college students.

2.The computer grade examination certificate is one of the criteria that employers look at when recruiting.

3.To solve the Shanghai household registration, you must pass the computer grade examination certificate or pass the NIT test.

4.Passing the Level 2 (C language) exam allows you to be exempted from the "Programming" course in the self-study exam.

5.If you pass the computer grade examination certificate, you can be exempted from the professional title computer test when evaluating the title.

The C language test is divided into a written test and a computer-based test, the written test has more concepts and requires a lot of memorization, and the computer-based test programming is a bit difficult, and you have to take at least two months to complete the written test and computer-based test. If you are engaged in computer work, it is quite useful, and some companies can add an additional 200 yuan to your monthly salary when they see that you have this certificate. But if you don't work in this area, you don't need to take the exam, it's a waste of time, because even if you don't do programming, you will have very little knowledge of the C language, let alone if you don't work in computers, so you might as well take your own professional certificate.

It's still very useful.,For example, many electronics majors require 2 and.。 So it's better to pass.

If you have a solid foundation, it is not difficult.

Multiple-choice questions are more complicated, and it is necessary to memorize the knowledge points.

The rest of the C language knowledge should also be familiar.

Then fill in the blanks for program correction and program design.

All require a certain programming foundation.

In addition, as long as the standard answer is different, you will be judged wrong, but it will not be very difficult As long as you understand the meaning of the program, it is still relatively easy to the last one is a more basic program design, as long as it meets all his test data, even if the subjective questions have a total of 60 points, if the foundation is solid, about 50 points or more is not difficult, and the rest of the multiple-choice questions can be mostly correct.

So as long as the foundation is solid, it is not difficult!

Although it is not very useful, you will not go wrong with the exam, because some jobs require computer literacy, and such a certificate is required.

As long as it is not difficult to learn by heart, it is useful for science and engineering, you can learn more about computer programming, but it is not very useful for liberal arts, but it is best to learn office software!

The second-level certificate indicates that the holder has basic computer knowledge and basic application ability, and can be engaged in the preparation of computer programs, primary computer teaching and training, and the business and marketing of computer enterprises.

In my own experience, Level 2 is not difficult, after all, it is not very difficult!

In this competitive society, multiple certificates are one more stepping stone!

C is the simplest and most difficult language.

Simple: It's because it's the foundation of other programming languages, but it's really easy to learn.

The premise is that you have to study seriously and have good logical thinking.

Difficult: because it is done if you want to find a job. You must be required to learn deeply. And this depth basically refers to the integration of computers.

What China imports the most is those integrated chips. And the pointer part of the C language is not very easy to grasp.

c is indeed a more useful thing. If your work or study involves the field of computing.

It's best to learn the C language.

Level 2 C. That is true.. It is composed of C language module + level 2 common subject module (data structures and algorithms).

If you think you're good at learning and you're willing to memorize data structures and algorithms. Basically, I can get by.

In addition, the data structure and algorithm are explained.

If you want to learn, it's still relatively rare.

It's still easy to memorize just because of the exam.

But seriously, Level 2C is relatively simple.

As for the pass rate, you can't find this thing at all.

So, there's nothing I can do about it.

Whether it's useful or not depends on what you want to do, and if you learn it well, it's trivial to find a job or something.

The second level is also better (listen to what the senior sister said), and the pass rate is not known.

If you have the heart to learn and learn seriously, you will definitely pass.,After the second-level C, it's just the basics.,If you want to program, you need to learn in depth.。

C is the basic language of computer programming, which is very helpful for learning other advanced languages in the future, and the powerful iPhone is also written in object C.

My C is self-taught.,Use Tan Haoqiang's book (third edition),The second level has passed,However,Friends also gave a little help,The pointer in the second level is the key and difficult,The structure is the difficulty,Of course, the array must also be mastered,The content of the first 3 chapters,Basically, it only accounts for a little score,The key is the content of the next few sheets,Learn C,Pointers must be mastered,Don't understand the pointer is equivalent to not mastering the essence of C,Some are just such as segments and the like are generally not tested。

The written test part is almost the same as looking at the basic content, practice is still very important, C is the computer language, like English to speak more, C must be more on the computer, practice to test the truth, there are program fill-in-the-blank questions, program modification questions, program design questions.

Program fill-in-the-blank questions generally involve the printf() function and the scanf() function; variables, operators, and expressions; Basic knowledge of selection structures, cyclic structures, functions; Points, structs, files, and more. Program modification questions generally involve logic and (&& and logic or (||the mixing of uses; a mixture of the divisibility operator ( ) and the remainder operator (%); A mixture of assignment signs (=) and double equal signs (==; The function type identifier is not specified; type coercion; variable initialization, etc.; Programming questions generally involve the representation of digits of numbers; determination of prime numbers; Numeric conversion string algorithm; bubbling sorting method; Choose a sorting method, etc.

These are all written by me with my heart, very hard, I hope it will help you

Variable types, arrays, loops, sorting algorithms, lookup algorithms. This is the point of the C language. Level 2 is nothing more than testing these things...

The best way to learn computer languages is to do more hands-on, write more small programs, and find problems from the program.

If you just think about level 2, it's very simple, you don't need to be very clear about every knowledge point, and ordinary people can't do it. It's best to practice a lot and write more programs. You'll have to write at least 3,000 lines to get started. Our teacher said it was 7000 lines to get started.

Reading books is very important, C language pays attention to details, you have to think more, start with the simplest example questions in the book, understand line by line, learn C quickly, not difficult.

Reading books is a must, it is recommended to practice while reading books, and run the programs on the books by yourself to gain more.

Newcomers can only look at it from the beginning.

The content of the Level 2 exam is not much, and it is divided into a written test and a computer-based test;

Talk about the written test: focus on comprehension, no need to memorize, including the content of the exam array, structure, function, pointer, input and output, etc., and some are based on computer applications, which has little to do with C, there are word, excell, ppt operations.

Lecture on computer-based test: It is very easy to pass the written test, and the computer-based test is divided into 3 questions, 2 are 60 points for filling in algorithms or cyclic conditions, and the third programming question is 40 points.

To ensure that the last one is all right, that is, the result is correct after running, and it can be operated in the examination room, I think the goal is 100 points.

So, first look at the concepts in the book, about: defining arrays, variables, structs, and then how to use what you define, followed by array operations, functions, pointers, loop statements, select statements, structs, conjunctions, enumerations, file operations, and so on.

C is not difficult, the difficult thing is to be diligent, first look at the example questions, and then do the questions, the computer test must go to the computer operation, if it is to do a draft, the debugging is not proficient in the exam is also a tragedy. The combination of watching and practicing, it is difficult not to do well.

Practice on the computer and practice the algorithm.
