Is It Advisable to Write Code from Scratch Without Libraries in C/C and Assembly Language?

When deciding whether to write code from scratch without using libraries, especially if you have a solid understanding of C/C and assembly language, and a strong grasp of computer fundamentals, it's crucial to consider your situation and goals. This article explores the pros and cons of writing code from scratch versus leveraging existing libraries, and provides insights into how to decide what approach is best for different scenarios.

For a Hobby: Go Have Fun!

When you're programming purely for fun, the sky's the limit. Writing code from scratch is a fantastic way to explore new concepts and deepen your understanding of how the computer operates. There's a sense of accomplishment in creating something from the ground up, and no external pressures. The freedom to experiment allows you to challenge yourself and possibly come up with innovative solutions. So, for a hobby, writing code from scratch is not only advisable but highly recommended.

For School: Sometimes, It's a Requirement

When it comes to school, things can get a bit more complex. Depending on the course and project requirements, writing code from scratch may be necessary. Here, the ultimate goal is often to learn and apply theoretical knowledge to practical scenarios. By writing code from scratch, you gain a deeper understanding of how algorithms and data structures work, and you can build a robust foundation in programming.

That being said, there are some downsides to be aware of. Writing software from scratch can be time-consuming, making it difficult to meet deadlines. Additionally, your code may initially be less efficient or less optimized than code that leverages proven libraries. However, if your instructor specifically requires that you write everything from scratch, it's essential to follow the assignment guidelines to ensure you either receive a zero or get kicked out.

For Work: Not Advisable Unless Time-Sensitive

When it comes to work, the stakes are higher, and constraints are tighter. Writing code from scratch is not advisable for most projects in a professional setting unless you have a very short timeframe or a specific requirement to experiment with something truly novel. Real-world applications often rely on robust, tested, and efficient code, which is why developers typically rely on established libraries and frameworks.

Here are a few key reasons why relying on libraries is more beneficial in a professional setting:

Efficiency and Time-Saving: Libraries provide well-refined, optimized functions and classes that can significantly reduce development time. They often include features that you might spend weeks or months implementing on your own. Quality and Reliability: Libraries have been extensively tested and used in countless projects. They are much less likely to contain bugs, ensuring that your project is more stable and reliable. Security: Libraries are regularly updated with security patches, reducing the risk of vulnerabilities in your code. Community Support: When you encounter issues, you can seek help from a community of other developers who have faced similar problems. Maintainability and Scalability: Code that leverages libraries is generally easier to maintain and scale, making it a better choice for long-term projects.

Conclusion: Balancing Flexibility and Efficiency

Writing code from scratch without libraries can be an enriching and educational experience, especially when it comes to school or hobbies. However, in professional settings, it's often more practical and efficient to leverage existing libraries and frameworks. Understanding how to write robust, high-performance code from scratch can still be a valuable skill. By combining this knowledge with the efficiency and reliability of existing tools, developers can create high-quality, maintainable, and secure software projects.
