What are the performance implications of parameter passing in programming?
Parameter passing can significantly affect performance, especially in terms of memory usage and execution speed. By value vs. by reference can lead to different outcomes.
Can you explain the difference between passing by value and passing by reference?
Sure! Passing by value means a copy of the variable is made, while passing by reference means a reference to the original variable is used. This can impact memory and speed.
Which method is generally more efficient?
Passing by reference is often more efficient for large data structures since it avoids copying the entire structure, saving time and memory.
Are there any downsides to passing by reference?
Yes, passing by reference can lead to unintended side effects since changes to the parameter affect the original variable.
