How do std::vector iterators compare to other container iterators in C++?

How do std::vector iterators compare to other container iterators in C++?

std::vector iterators are random access iterators, allowing direct access to elements. They are faster than list iterators, which are bidirectional, but slower than array pointers.

What are the advantages of using std::vector over other containers?

std::vector offers dynamic sizing, contiguous memory storage, and efficient access to elements, making it ideal for many use cases.

Can you explain the performance differences between std::vector and std::list?

Certainly! std::vector provides faster access and better cache performance due to contiguous memory, while std::list allows for efficient insertions and deletions.

When should I prefer std::deque instead of std::vector?

Use std::deque when you need efficient insertions and deletions at both ends, as std::vector is slower for these operations.
