What are iterators and algorithms in C++?

Can you explain what iterators are in C++?

Sure! Iterators are objects that allow you to traverse through the elements of a container, like arrays or lists, without exposing the underlying structure.

How do iterators differ from pointers?

While pointers can be used to access elements in an array, iterators provide a more abstract way to navigate through different types of containers, ensuring type safety and flexibility.

What are some common algorithms used with iterators?

Common algorithms include sorting, searching, and transforming data. The Standard Template Library (STL) in C++ provides many built-in algorithms that work seamlessly with iterators.

Can you give an example of using an iterator with an algorithm?

Certainly! For example, you can use the std::sort algorithm with iterators to sort a vector: std::sort(vec.begin(), vec.end()); This sorts the elements in the vector in place.
