Is Copying Code from the Internet Reasonable for Programmers?

In the IT community, a common joke is that the two shortcuts programmers know best are Ctrl+C and Ctrl+V, and many programmers even humorously call themselves "code movers" rather than code creators.

A recent Zhihu question that attracted over 30,000 views asked, "What happens when a programmer is caught by their boss copying code from the internet?" This sparked many responses from developers.

People often wonder why programmers can copy code and still earn high salaries, suggesting that the practice is somehow easy and lucrative.

Is copying code from the internet reasonable?

Copying code is essentially a form of code reuse, which is ubiquitous in software development. It is not merely plagiarism; rather, it is a practical way to leverage existing solutions.

However, copying entire projects or copyrighted code without permission can lead to legal disputes if the original rights holder discovers the infringement.

Properly using open‑source code avoids “reinventing the wheel,” frees developers to focus on higher‑value work, accelerates development, and maximizes resource utilization.

From a manager’s perspective, the primary concern is whether the result meets the project’s goals. As long as the solution delivers value, supervisors often praise the developer regardless of the method used.

Therefore, whether copying code is acceptable depends less on policy and more on whether the borrowed snippet solves the problem, speeds up the project, and reduces costs.

Elegant copying matters: developers should integrate external code thoughtfully, ensuring it fits the project’s architecture and standards.

Finding the right snippet among millions of lines of code requires solid fundamentals and deep familiarity with the language and its ecosystem.

The most important point is to understand not only *what* to copy but *why* to copy it, and how to adapt it into one’s own logic to solve real problems.

In summary, programmers should view copying as a learning process: trace the source, grasp the underlying principles, and transform the code into a robust, maintainable solution, thereby becoming truly skilled developers.
