std::ranges::zip_view (C++23 Addition)

#include <ranges> auto zv = std::ranges::zip_view(names, scores);

// CodeNebula - C++23 Example: std::ranges::zip_view
// Compile: g++ -std=c++23 -Wall -Wextra -o example ranges_zip_view.cpp
// Note: Requires GCC 13+ / Clang 17+

// std::ranges::zip_view combines multiple ranges into a single view of tuples,
// where each tuple contains one element from each source range. Iteration stops
// when the shortest range is exhausted.
