When should I use for loops in programming?

When should I use for loops in programming?

For loops are ideal when you know the number of iterations in advance, like iterating over a list.

Can you give me an example of a for loop?

Sure! Here's a simple example in Python:

for i in range(5):
    print(i)

This will print numbers 0 to 4.

What about while loops? When should I use those instead?

While loops are better when the number of iterations isn't known beforehand, like waiting for user input.

Are there any performance differences between for loops and while loops?

Generally, for loops can be more efficient for fixed iterations, but the difference is often negligible in most cases.
