What is the compatibility of iterators in C++ std::vector?

Can you explain the iterator compatibility in C++ std::vector?

Sure! In C++, std::vector provides random access iterators that are compatible with each other. This means you can use different iterators to traverse the same vector.

What do you mean by random access iterators?

Random access iterators allow you to access elements in a vector using an index, similar to array indexing. You can move forward or backward in constant time.

Are there any limitations to using iterators with std::vector?

Yes, iterators become invalidated if the vector is modified, such as when elements are added or removed, which can lead to undefined behavior.

How can I safely use iterators with std::vector?

To safely use iterators, avoid modifying the vector while iterating over it. If you need to modify it, consider using a copy of the vector or iterating in a way that doesn't invalidate the iterators.
