Debugging is a term commonly used in the field of information technology. Despite being a technical jargon, it plays a crucial role significantly impacting the quality of a product. Therefore, every programmer must have a clear understanding of Debugging. If you are unfamiliar with what Debugging is and its role in programming, refer to the article below.
Meaning and Purpose of Debugging
Literally, a Bug is an insect, and most insect species are harmful. In computing, the term 'Bug' was coined when the first real insect disrupted the electronic circuitry of the early digital computers. Since then, 'Bug' is used to denote technical errors in programming that prevent a program from executing correctly or produce incorrect results.
Naturally, where there are pests, there must be pest control; where there are errors, there must be error correction. The term 'Debug' implies the process of searching, reviewing errors, or identifying the causes of errors to find ways to rectify them. This is a fundamental technique in programming because it not only helps eliminate errors but also allows programmers to gain a deeper understanding of the execution of their written programs.
Debugging Methods
In the programming world, besides manually inspecting errors with the naked eye, several widely used Debugging techniques include:
- Debugging Tool: Using tools for Debugging. Such tools are called Debuggers and are typically integrated into IDEs (software aiding programmers in software development). Additionally, there are hardware Debuggers designed for embedded systems, as embedded designs are often created on distinct platforms, requiring specific Debuggers to serve their unique applications.
- Printlining: Adding extra lines of code to print the necessary information during execution. This method is somewhat cumbersome as it requires modifying the source code, and the added lines need to be removed after Debugging.
- Logging: Creating a form to record information after program execution, then using that information to identify the cause of errors. This method is often applied in real-world environments, meaning when your application is in use by customers, as you cannot alter the source code or use debugging tools.
Now, you understand what Debugging means and its role in programming, right? As a programmer, Debugging is unavoidable. When you lack experience, Debugging can be a daunting task, even something you may fear, as large programs can generate many complex errors. But regardless, you must face it, ponder on it, and through that, quickly enhance your skills. Wishing you a swift journey to becoming a professional programmer!
