How do I write range factories generating sequences?

In C++, range factories are a useful feature for generating sequences of numbers or other types of data. By using range factories, you can create sequences that can be easily manipulated and iterated over. This helps improve readability and maintainability of your code.

Example of Range Factory for Generating Sequences

Here’s an example of how to create a simple range factory that generates a sequence of integers:

#include #include #include auto generate_range(int start, int end) { return std::views::iota(start, end); } int main() { for (auto i : generate_range(1, 10)) { std::cout << i << " "; // Output: 1 2 3 4 5 6 7 8 9 } return 0; }

This example demonstrates how to create a range from 1 to 9 using the `std::views::iota` from the C++20 standard library.
