What are the differences between C++11 vector iterators and arrays?

C++11 vector iterators provide dynamic sizing and flexibility, while arrays have fixed sizes and are less versatile.

Can you explain how to use vector iterators in C++?

Sure! You can use vector iterators with the begin() and end() methods to traverse elements. For example:

std::vector<int> vec = {1, 2, 3};
for (auto it = vec.begin(); it != vec.end(); ++it) {
    std::cout << *it << ' ';
}

Are there any performance differences between using vectors and arrays?

Yes, arrays can be faster for fixed-size data due to less overhead, but vectors offer better performance for dynamic data management.

What are some common use cases for vectors over arrays?

Vectors are ideal for situations where the size of the data can change, such as when reading user input or handling dynamic datasets.
