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;
}
