Check out the new article: From Basic to Intermediate: Passing by Value or by Reference.
In this article, we will practically understand the difference between passing by value and passing by reference. Although this seems like something simple and common and not causing any problems, many experienced programmers often face real failures in working on the code precisely because of this small detail. Knowing when, how, and why to use pass by value or pass by reference will make a huge difference in our lives as programmers. The content presented here is intended solely for educational purposes. Under no circumstances should the application be viewed for any purpose other than to learn and master the concepts presented.
One of the most common sources of confusion and mistakes in programs written by beginners is knowing when to use passing by value and when to use passing by reference in functions and procedures. Depending on the situation, passing by reference may be more practical. However, passing by value is often safer. But when should you choose one over the other? Well, dear reader, it depends. There is no absolute or definitive rule for this practice. In some cases, passing by reference is indeed the best choice, while in others, passing by value is the appropriate approach.
Typically, the compiler attempts to make choices that result in the most efficient executable code possible. Nevertheless, it is crucial that you understand what each scenario demands so that you can write code that is both safe and efficient.
