Finding mistakes in software and getting rid of them is essential and it is a process known as “debugging”.
What is Debugging
Debugging refers to the process of finding software bugs and resolving them. It does not only hold with bugs but likewise with errors and abnormalities. That process is done with the help of debugging tools. Debugging does not only find and fix bugs. It also enables programs to operate appropriately based on the specifications set for it.
The process is time-consuming and often frustrating. However, it is also a means for you to review your code after developing it. Debugging may be done by the elimination process first. Find where the problem is step by step. Where there is a problem, there is a bug. Start from the beginning to the end.
Debugging is a very intricate process. There are times that it can consume more time as when you wrote the code.
Developing software programs undergo heavy testing, updating, trouble shooting and maintenance. Typically, the software contains errors and bugs, which are routinely removed. And executed to identify and rectify issues. Large software programs, which include millions of source code lines, are divided into small components. Hence, followed by the program as a whole.
How Debugging is Done
There are times when software developers do not always get what they expect to get when they wrote the code. In other words, if the code does not do as the developers expected them to do, figure out why this is so. And this is made possible by using debugging tools. But make sure you use the right tools for the task. These debugging tools are referred to as debuggers.
But then the use of debugging tools does not mean it will just reveal the problem right away. You still need to do the process step by step with the help of a debugger. This way, the exact part where the problem is will be identified. Once the problem has been detected and found, you can then begin with the fixing process. Make the necessary corrections and other fixes to resolve the issue.
It takes skill and lots of practice to use a debugger properly and hence generate effective and reliable results. And this is one thing every developer must learn.
The Debugging Process
- Reproduce the problem.
- Get as much information as you can get from the user to describe the bug.
- Gather as much data about the program. When the bug appears, get a program snapshot.
- Find the cause of the bug based on your analysis of the program snapshot.
- Find ways to resolve the issue. At the same time, make sure that other new bugs will not occur.
To debug a program, the user has to start with a problem, isolate the source code of the problem, and then fix it. Despite it being a time-consuming and intricate process, debugging is a vital process that must be observed. It is sort of a quality control thing where you test the product, find out what is wrong with it. If it does not function as it should, then figure out why. In short, debugging means finding errors and bugs, then resolving it. It is a bit frustrating to find out that after your hard work in creating a brilliant block of code, it ends up with errors.
There are ways to find errors a little easier, though. Such things as modern code editors help find syntax errors. Errors which cause programs to crash are harder to find, though. These are called semantic and runtime errors. These types of errors can also produce incorrect outputs and can make programs run endlessly. Debugging helps us understand why the code is behaving in such unexpected ways.
A code is a computer language which programmers write. Since programmers are humans, they are not perfect, of course. This is the reason why, naturally, the codes they write have flaws. They commit mistakes, too. And this is where debugging comes in. With all the complexities of writing code, it is not unusual for it to have bugs. That is why the debugging process is there – to find bugs and remove them. Plus, making sure that as much as possible, no more new bugs will occur.
