CS253: Problem Solving with C++

Local Static Variables

#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';
}

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