What is memory management in pass-by-value?

What is memory management in pass-by-value?

Memory management in pass-by-value refers to how data is handled when passed to functions. In this method, a copy of the variable is made, which means changes to the parameter inside the function do not affect the original variable.

Why is pass-by-value important in programming?

Pass-by-value is important because it prevents unintended side effects. It ensures that the original data remains unchanged, which can help maintain data integrity and make debugging easier.

Can you give an example of pass-by-value in a programming language?

Sure! In languages like Python, when you pass a number to a function, a copy is made. For example, if you have a function that adds 1 to a number, the original number outside the function remains unchanged.

What are the drawbacks of pass-by-value?

One drawback is that it can lead to increased memory usage, especially with large data structures, since copies of the data are created. This can also impact performance.
