Fail-Proof Tips and Tricks for Debugging Codes

No developer likes to see bugs in their codes, You ask any developer they’ll tell you debugging codes is worse than actually writing the code. 

Imagine after writing thousands of lines of code and you decide to run it and boom! There’s a bug.

The only Organism on this earth that likes bugs is definitely not the developer, It’s the Spider.

If a Chef gets the ingredients in his cooking wrong, This would be just like starting over.

That’s the reality of bugs and code for the developer.

What Are Software Bugs?

What Are Software Bugs?

Software bugs are flaws in design, development, or operation of computer software that cause an incorrect or unexpected output. The process of finding and correcting bugs is termed “debugging” and often uses formal techniques or tools to pinpoint bugs.

Bugs arise from various factors like; Errors in interpreting user’s requirements, mistakes by the programmer (both frontend and backend developers) when writing the code, or unforeseen interactions between different parts of the software.

So some bugs are fixed by making simple changes to the code, while others require more extensive reworking of the software.

Also In some cases bugs can have serious consequences, such as causing data loss or security vulnerabilities.

Bugs in codes have been traced to cause casualties and even cost the USA $59 billion annually, about 0.6 of their GDP(gross domestic product).

Types Of Software Bug Errors

		Types Of Software Bug Errors

There are three Major types of software bug errors depending on various factors that caused the error.

  • Syntax errors: These are errors in the code itself, such as incorrect spelling or missing punctuation. Humans are prone to make mistakes, syntax errors are mostly not unavoidable.
  • Logical errors: These are errors in the logic of the code, because where you write the code correctly but it does not produce the intended result.
  • Runtime errors: These are errors that occur while the code is running, such as dividing by zero or trying to access an index of an array that is out of bounds. which are errors that can be caused by both human and machine factors. 
  • Resource leaks: Resource leaks are bugs that occur when the code fails to properly release resources, such as memory after they are no longer needed.
  • Security vulnerabilities: These are bugs that can be exploited by attackers to gain unauthorized access to a system or its data. This is a costly bug that should be avoided at all costs. 
  • Performance issues: These are bugs that cause the code to run inefficiently, resulting in slow performance or other issues.
  • Compatibility issues: These are bugs that cause the code to work differently on different platforms or in different environments.

Implications Of Software Bugs

Implications Of Software Bugs

Ask any programmer, The greatest Pain in their neck are bugs. This pain in the neck comes with great consequences, which I’ll be covering in this module.

Software bugs have a wide range of implications, depending on severity and nature of the bug, also the context the software is used. Some potential implications of software bugs include:

  • Reduced productivity: Bugs can cause the software to crash, freeze, or otherwise become unresponsive, which can be frustrating for users and disrupt their workflow because No user likes an app that crashes.
  • Data loss: Bugs cause data to be lost, or corrupted, which is a significant problem for sensitive data. In a worst-case scenario, The data were not backed up.
  • Security vulnerabilities: Bugs create vulnerabilities that can be exploited by hackers or malicious software, potentially leading to security incidents. In the cases of blockchains getting compromised because of bugs in their codes.
  • Damage to reputation: If a bug causes problems for a large number of users, it can damage the reputation of the software and the company that developed it.
  • Financial losses: Bugs can cause financial losses for companies and individuals if they result in lost sales, legal liability, or other financial consequences.

Tips For Debugging Software Bugs

Tips For Debugging Software Bugs

There are many strategies you can use to debug software effectively. Here are a few tips that may be helpful:

  1. Isolate the problem: try to identify exactly where the issue is occurring and what is causing it. This is achieved by adding print statements and using a debugger to step through the code.
  2. Reproduce the problem: if you can consistently reproduce the issue, it will be much easier to debug. Try to identify any patterns or common factors that may be contributing to the problem.
  3. Check for error messages: many programming languages provide helpful error messages that can give you a clue about what is going wrong. Be sure to check for these and try to understand what they are telling you.
  4. Divide and conquer: if you are having trouble figuring out where the problem is occurring, try breaking the code down into smaller pieces and testing each piece individually. This can help you narrow down the problem and identify the specific lines of code that are causing the issue.
  5. Get help: don’t be afraid to ask for help if you are stuck. Other developers or online communities can often provide valuable insight and assistance.
  6. Google is your Partner- There is virtually an answer for every question you ask on google, Why? There’s someone out there that has been in your situation. Platforms like GitHub or StackOverflow have a community of developers that can help review your problem.

So there is no end in sight for a developer’s reality without bugs.

You only have to learn to manage them but of course, debug them with any of the tips shared above.

As a beginner in the software development world, Never neglect the tools of debugging.
