Can you explain C++ vector iterators with examples?

Can you explain C++ vector iterators with examples?

Sure! In C++, a vector iterator allows you to traverse the elements of a vector. 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;
}

What does this code do?

This code initializes a vector with integers 1 to 5 and uses an iterator to print each element.

Are there other types of iterators in C++?

Yes, C++ has several types of iterators, including reverse iterators, constant iterators, and more.
