Have you had experience using standard containers and STL algorithms in your projects?

Yes, I have experience using the Standard Template Library (STL) in C++.

STL provides many containers (vector, list, map, set, etc.) and algorithms (sort, find, transform, etc.) that greatly simplify working with data.

For example, to sort a vector of numbers, you can use:

#include <vector>
#include <algorithm>

std::vector<int> numbers = {4, 2, 5, 1, 3};
std::sort(numbers.begin(), numbers.end());

I also often used map for storing key-value pairs and algorithms for searching and processing elements.

Using STL allows writing more compact, efficient, and readable code, avoiding manual memory management and implementation of basic data structures.
