All subsequent times, the same memory location and current value are used. Why use internal static objects? Faster programs • Counters Better alternative to global objects 1/27/2003 Svetlozar Nestorov, CS 116: Intro to Programming II 5 Example void drink() { static int count(0); static const int max = 5; if (count >= max) { cout << “Sorry, too many drinks!”;
