What are the best practices for using iterators in C++?

What are the best practices for using iterators in C++?

Some best practices include using standard library iterators, avoiding raw pointers, and ensuring iterator validity.

Can you explain why avoiding raw pointers is important?

Avoiding raw pointers helps prevent memory leaks and dangling pointers, making your code safer and more maintainable.

What are some common mistakes developers make with iterators?

Common mistakes include invalidating iterators by modifying the container, using iterators beyond their scope, and not checking for end conditions.

How can I ensure my iterators are valid?

You can ensure iterator validity by not modifying the container while iterating and by using algorithms that respect iterator validity.
