How do I use iterators in C++11?

Can you explain how to use iterators in C++11?

Sure! In C++11, iterators are used to traverse elements in a container like vectors or lists. They provide a way to access elements without exposing the underlying structure.

What are the different types of iterators available in C++11?

C++11 provides several types of iterators: input iterators, output iterators, forward iterators, bidirectional iterators, and random access iterators. Each type has its own capabilities.

Can you give me an example of using a vector iterator?

Certainly! Here's a simple example:

#include <iostream>
#include <vector>

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

This code iterates through a vector and prints each element.

What are the advantages of using iterators?

Iterators provide a uniform way to access elements in different containers, promote code reusability, and help in writing generic algorithms.
