Local Static Variables

(:source lang=cpp name=c.cc -inline:)

1. include <iostream>

using namespace std;

unsigned long next_id() {

        unsigned long id=800000000UL;
        return ++id;

}

int main() {

        cout << next_id() << '\n';
        cout << next_id() << '\n';
        cout << next_id() << '\n';

} (:sourceend:)

1. Run it
2. Make id static outside of next_id()
3. Make id static inside of next_id()
