How do I reserve capacity ahead of time with std::set in performance-sensitive code?

In performance-sensitive code, it is important to manage your data structures efficiently. Although std::set in C++ does not allow for reserving capacity directly, you can optimize its use by knowing your expected number of elements and avoiding rebalancing costs associated with insertions. This article provides insights on how to leverage std::set effectively.

// Example showing usage of std::set in performance-sensitive code #include #include int main() { std::set numbers; // Simulate inserting several elements for (int i = 0; i < 10000; ++i) { numbers.insert(i); } std::cout << "Number of elements in the set: " << numbers.size() << std::endl; return 0; }
