What are STL algorithms and how do they work?

STL algorithms are part of the Standard Template Library in C++. They provide a set of functions for operations like sorting, searching, and manipulating data.

Can you give me an example of a sorting algorithm in STL?

Sure! The std::sort function is commonly used to sort elements in a range. For example, std::sort(vec.begin(), vec.end()); sorts the elements in the vector vec.

What about searching algorithms?

For searching, you can use std::find to locate an element in a range. For example, std::find(vec.begin(), vec.end(), value); returns an iterator to the found element.

Are there algorithms for manipulating data as well?

Yes, STL provides algorithms like std::transform for applying a function to a range of elements, and std::copy for copying elements from one range to another.
