How do I use advanced iterators in C++?

Advanced iterators in C++ allow you to traverse and manipulate collections more efficiently. Are you looking for specific types?

Yes, can you explain the difference between input, output, forward, and bidirectional iterators?

Sure! Input iterators read data, output iterators write data, forward iterators can read and write, and bidirectional iterators can move both ways.

What about random access iterators?

Random access iterators allow you to access elements at any position in constant time, similar to pointers. They're used with containers like vectors.

Can you give me an example of using a random access iterator?

Certainly! Here's a simple example using a vector:

#include <vector>
#include <iostream>

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 code iterates through the vector using a random access iterator.
