Answer
STL commonly refers to the C++ standard library’s generic containers, iterators, algorithms, and function objects. • Containers store values using defined ownership and complexity rules. • Iterators connect algorithms to sequences. • The full C++ standard library also includes facilities beyond the original STL design.
💡 C++ Example
#include <algorithm>
#include <vector>
std::vector<int> values{3, 1, 2};
std::sort(values.begin(), values.end());
