How do I use iterators with std::vector in C++11?

Can you explain how to use iterators with std::vector in C++11?

Sure! In C++11, you can use iterators to traverse a std::vector. You can use begin() and end() methods to get the start and end iterators.

Can you show me a simple example of using iterators with std::vector?

Of course! Here's a simple example:

#include <iostream>
#include <vector>

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};
    for (auto it = vec.begin(); it != vec.end(); ++it) {
        std::cout << *it << " ";
    }
    return 0;
}

This will print the elements of the vector.

What are the advantages of using iterators over traditional indexing?

Using iterators provides more flexibility and can work with different container types. They also help avoid out-of-bounds errors.

Are there any specific iterator types in C++11 I should know about?

Yes! In C++11, you have different types of iterators like random access, bidirectional, and forward iterators, each with specific use cases.
