C++: Iterator vs Algorithms

What is the difference between iterators and algorithms in C++?

In C++, iterators are objects that allow you to traverse through a container, while algorithms are functions that operate on these containers using iterators.

Can you give me an example of how to use an iterator with an algorithm?

Sure! For example, you can use the std::sort algorithm with iterators to sort a vector: std::sort(vec.begin(), vec.end());.

Are there different types of iterators in C++?

Yes, C++ has several types of iterators: input, output, forward, bidirectional, and random access, each with different capabilities.

How do I choose the right iterator for my algorithm?

Choose an iterator based on the requirements of the algorithm. For example, use random access iterators for algorithms that require fast access to elements.
