When you declare an iterator to work with a container, the compiler automatically chooses the right type.

Question

Quizplus · Accepted Answer

This is true. When you declare an iterator for a container, the compiler automatically chooses the appropriate type based on the container's type. For example, if you declare an iterator for a vector, the compiler will choose a random access iterator, whereas if you declare an iterator for a list, it will choose a bidirectional iterator.
