This article mainly explains "what are the characteristics of C++ language", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what are the features of C++ language"?

Debugging Technology of Visual C++

Check the code until dizzy and find no errors. As soon as you run the program, it crashes, so you have to sacrifice the magic weapon: debugger. The Visual C++ debugger can be called the * debugger on Windows platform, and the Visual C++ debugger can also debug programs written in other languages such as Delphi and Java, which is powerful.

Although the Visual C++ debugger is so powerful, it can only help you find some hidden logic errors and can do nothing about programming and structural flaws. Visual C++ debugging techniques most commonly used by programmers are setting breakpoints, tracking call stack and disassembling debugging. Other compiler functions are auxiliary tools in debugging, because disassembly debugging requires programmers to have assembly language knowledge and language infrastructure, which will not be introduced here.

Prerequisites for debugging C++ language

A common feature of professional debuggers is that they are also good developers. Obviously, if you're not a good developer, you can't be a debugging expert, and vice versa. Here are the areas you need to be proficient in order to be a high-level, or at least qualified, debugger or developer.

1. Understanding the project: understanding the project is an essential element to prevent errors in the user interface, logic, and performance. By knowing how and where the various functions are implemented in various source files, you can narrow your search and quickly find out what the problem is.

two。 Mastering the language: to master the languages used in the project, the debugger (developer) needs to know not only how to program in these languages, but also what these C++ languages do in the background.

3. Mastering technology: an important step in solving thorny problems is to grasp the essentials of the technology used, which does not mean that you have to know all the details of the technology used, but that you should have a general understanding of the technology used, and more importantly, when you need more detailed information, you should know exactly where to look.

4. Operating system and CPU: any project actually runs on a specific operating system and a specific CPU, and the more you know about the operating system, the more helpful it is to find errors; in theory, by mastering assembly language, you can debug and solve any bug.

No matter what kind of work they are engaged in, as long as they are often engaged in technical work, they must continue to learn to keep up with the development of technology, not to mention want to do a better job or to be at the forefront of technological development. Often read excellent technical books and magazines, write more practical programs, read the code of other good developers, and do some disassembly work, will effectively help you improve your level of development and debugging (especially if you combine the four organically).

Debugging process

It is difficult to determine a debugging process that can solve all errors, but the debugging process proposed by John Robbins should be said to be the most practical:

1. Copy error

two。 Description error

3. Always assume that the mistake is your own problem.

4. Break down and resolve errors

5. Think creatively.

6. Use debugging aids

7. Start debugging work

8. The check error has been corrected

9. Learning and communication

Describing the mistakes can help to correct them, and at the same time, you can also get help from colleagues. Gradually narrowing down the scope of the problem and eliminating code segments where there are no errors until the problem is found is a universally applicable way to solve all problems. Some strange errors require you to shift your attention from the code heap to other aspects such as the operating system, the hardware environment, and so on.

Making good use of various debugging C++ language aids can save you a lot of time, and some tools themselves won't give you a chance to make some mistakes. When you solve a bug, stop and think about what caused you (or him) to make such a mistake, and how to avoid it in the future? Remember that a debugger is just a tool, like a screwdriver. It only does what you tell it to do. The real debugger is the debugging idea in your head.

At this point, I believe you have a deeper understanding of "what are the features of C++ language". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
