Now I ve just finished Level 4 in Computer Science, and I can t understand how hard it is to learn C

As long as you have a little computer foundation, C language is actually not difficult to learn at all, and level 4 should be enough. Learning computer languages is done in a certain order, so if you don't know where to start, buy some textbooks and read them. Also, there are more people who use C++ nowadays, and C++ is not much more difficult to learn than C language, so you'd better learn C++.

C language: C Programming Tutorial C Programming

C++: C++ Programming (preferably 04 version).

It's not hard. First of all, we need to understand and learn. Then do more representative exercises and draw inferences from each other.

If it is convenient to go online, you can check some relevant information and exercises on the Internet, and practice more practically!

Back then, I had a buddy in a liberal arts class who taught himself C language and passed the second level of computer science, do you think it is difficult?

I am also self-taught in C language.

Beginners recommend Tan Haoqiang's C language programming textbook, which is simple and easy to understand.

But if you want to learn thoroughly, you have to apply it in your own practice... Hey.

There are four levels, and that's the highest level. It is divided into the following three categories;

Level 4 Database Engineer.

Evaluate database application system analysis and planning, database design and implementation, database storage technology, concurrency control technology, database management and maintenance, database technology development and new technology. Obtaining this certificate shows that candidates master the basic theories and technologies of database systems, can use SQL language to establish, maintain and manage databases, have the ability to use tool software to develop basic database application systems, and are competent in the maintenance, management and application development of small and medium-sized databases.

Level 4 Network Engineer.

Assess network planning and design, LAN networking technology, establishment of computer network information service system, computer network security and management. Candidates should understand the planning and management methods of large-scale computer network systems, have the basic ability of planning and design of small and medium-sized network systems, master the basic technology of small and medium-sized network system construction and equipment commissioning, and master the basic technology of maintenance and management of small and medium-sized computer network systems in enterprises and institutions.

Level 4 Software Testing Engineer.

Assess the basic concepts of software testing, structure coverage testing, functional testing, unit testing, integration testing, system testing, software performance testing, reliability testing, object-oriented software testing, web application software testing, compatibility testing, component testing, limit testing, and documentation testing. Candidates should be able to combine software testing process management platform and software analysis and testing tools to increase practical experience in software testing engineering, and be competent for the requirements of software testing positions.

There is no C language in computer level 4, and computer level 4 is already very advanced, and the test is taken after combining various professional fields! You can take the software engineer exam, and there are software engineers in level 4!

There is no special C language level 4 test, only the computer level test, and generally students in school who are not computer majors only need to pass level 2. In the future, there are more advanced ones, and if you want to take the test, you can consult with the teachers at the school. The teacher himself may also take the test.,For example, what computer level 6.。。。
