How do I use ranges libraries (range-v3) in C++?

The Range-V3 library is a powerful tool for working with ranges in C++. It provides a set of algorithms and range adaptors, allowing for more expressive and cleaner code. Below is a simple example demonstrating how to use the Range-V3 library.

#include #include #include #include #include int main() { std::vector numbers = {1, 5, 2, 4, 3}; // Use Range-V3 to filter and sort auto filtered = numbers | ranges::views::filter([](int n) { return n % 2 == 0; }); auto sorted = filtered | ranges::views::take(1); for (int n : sorted) { std::cout << n << " "; } return 0; }
