Ask for help with questions about the programmer exam

The Ministry of Labor has a special certification for programmers, but I don't think it's very useful, and the initial certification, which is the part of the exam for programmers, is very simple. Nothing to learn.

I'm also a five-year student, and I'm now graduating.

School can't teach you anything. If you want to be a programmer, you can read books and write something on your own. For example, mobile phone software, or chat tools and the like, depending on your preferences.

In the process of writing programs, you can get in touch with and learn new knowledge. The value of a teacher is better reflected when you encounter problems in your own writing.

Your biggest gain in school should be your problem-solving skills. When a question is put in front of you, the thought is not "no", "I haven't learned" and then give up, but "What is this?" "How to solve it?

Then find your problem, gradually refine, study, solve, and then discover new problems. Learn to look up information and ask questions.

In addition, it is recommended to lay a solid foundation. When I was looking for a job, I didn't see the interviewer ask me what my job title was. Just asked about some very simple principles.

For example, what is the difference between something defined by a macro in C++ and a constant const constant. There are also some problems with pointer manipulation.

Textbooks and other things, it is recommended that you go to the school library and find what you are interested in.

For the principle class, you can take a look at "In-depth Understanding of Computer Systems".

In there, it is recommended that you look at the basics of assembly, data structures, algorithms, etc.

The programmer's self-cultivation", "effective c++" and so on are quite good.

In my experience with companies, these are useless, and some companies may like some Microsoft and Oracle certifications, but in fact they are just used to increase their bargaining chips, and if they are not such companies, they are rarely looked at.

Practical ability is the most reflective, and the ability to solve problems when encountering is particularly important, but this depends on the accumulation of experience.

Do more at work, don't be afraid that you don't dare to do things if you haven't done them, you can ask more, but try not to refuse because you haven't done anything similar, resulting in the leader not having a good image of you and not improving yourself.

1. What is the test format of the soft test? What is the exam time?

Except for information processing technicians and multi-application production technicians, which take the form of a combination of written tests and computer-based operation tests, all other examinations are in the form of written tests. The examination implements the examination method of national unified syllabus, test questions, time, standards and certificates.

The Advanced Qualification Examination consists of 3 subjects: Comprehensive Knowledge, Case Analysis, and **; The Intermediate and Elementary Qualification Examinations consist of two subjects: Basic Knowledge and Applied Technology. The written test is scheduled for one day. The computer-based test will be conducted in batches.

The knowledge subject adopts multiple-choice questions, the test is 150 minutes, and candidates need to fill in the answer sheet with a 2B pencil; The Applied Technology subject adopts questions and answers, and the examination time is 150 minutes; The computer-based test lasts 150 minutes; The case analysis course uses questions and answers, and the examination time is 90 minutes; **The duration of the subject exam is 120 minutes. The maximum score for each subject is 75 points.

2. How many times a year does the soft test take? What are the dates of each exam?

In principle, the soft test is organized twice a year, and is held in the second and fourth quarters of each year. The types of exams in the first half of the year are different from those in the second half of the year, so most types of exams are held once a year.

3. Do I need academic qualifications and qualifications to participate in the soft examination? Do I have to pass the primary qualification examination to sit for the intermediate and advanced qualification examinations?

Due to the rapid development of information technology, computer software is the cause of young people, in order to select talents without sticking to one pattern, the soft examination does not set academic qualifications and qualifications, and regardless of age and major, candidates can choose the appropriate level and appropriate qualification according to their own technical level, but only one qualification can be applied for in an examination.

4. Is it difficult to take the soft test? What is the pass rate?

The soft test belongs to the national brand test at the professional level, and the test questions focus on job knowledge and skills (not endorsement), comprehensive and flexible, and creative, but as long as the candidates master the basic knowledge and skills required for the corresponding position, they will think that the exam is not difficult. It can be more difficult for people who memorize books by rote. Since the examination is open to the public, there are no academic qualifications, and only those who pass all subjects of knowledge and ability can pass, so the pass rate is not high.

The overall average pass rate for each level is about 25%, about 40% for primary qualifications, 20-30% for intermediate qualifications, and about 20% for advanced qualificationsThe level of applicants for the social opening examination varies greatly, and the level of everyone is not relatively close like that of the school examination, so there is no need to worry about the pass rate if you have mastered the basic knowledge and work experience.

The soft test is not a competition, as long as the score exceeds the passing standard, you can pass, and there is no pre-specified limit for the number of passers.

1) Basic knowledge of computer hardware and software.

In the worksheet shown in the figure below, if the final grade of the students is equal to 30% of the usual grade plus 70% of the test score, then fill in (3) in cell E2 and drag the fill handle to cell E7 (4) to automatically calculate the final grade of these students.

3）a．=c2*30%,d2*70%

b．= c2*30%:d2*70%

c = sum(c2*30%,d2*70%)d = sum(c2*70%:d 2*30%)4)a to the horizontal.

b Vertically.

c Hold down the shift key in a horizontal direction.

d Hold down the shift key in a vertical direction.

2) Programming.

Question 1 (15 marks in total).

Read the instructions and flowchart below, fill in the gaps in the flowchart (1) (5), and fill in the answers in the corresponding fields on the answer sheet.

Note] The easiest way to find the root of a continuous function f(x) (the solution of equation f(x)=0) is the dichotomy. To do this, it is first necessary to check the sign of the function value at several points, and if it is found that f(a) is the opposite of the f(b) sign (a<>).

The program test can only find 80% of the problems at most, so 40 80% + 50 80% = 108, which is closest to 100, so the total number of errors in the program can be estimated to be c, 100.

That's about it:

1. Programming for money.

If you're not interested in programming, your ** is bound to suck at writing. Not only will your career have no future, but your team will also suffer.

2. Lack of basic ability.

Written by people who are not familiar with programming concepts such as abstraction, polymorphism, interfaces, exception handling best practices, etc., are inevitably poorly designed, with poor readability and maintainability.

3. Be smart.

Some programmers like to be too clever and have multiple steps in a complex statement. This makes the ** very readable, and no one will like to maintain it.

4. I like to show off my newly learned technology.

When you learn something new, you naturally have a tendency to apply it right away. Be patient. Use it when you really need it.

5. Too many goals.

Programs that set too many goals for performance, memory usage, robustness, and reliability will take longer to develop, resulting in overly complex programs.

6. No refactoring**.

Software is an ever-evolving product. As the library grows, individual classes, methods, etc., become more and more complex. Lazy programmers are reluctant to refactor, resulting in over-complexity.

7. Malicious complexity.

Some programmers deliberately make their ** unusually complex in order to build their own territory. They do this to force companies to rely on them, and it's a ploy to protect jobs.

8. The most common technical mistake programmers make.

There are two strategies for designing software, one is to do it so simply that it is obviously free of defects. The second is that it is so complex that there are no obvious flaws. ”
