#include <iostream>

void test() {
    static int a[4];
    for (int i = 0; i < 4; ++i) {
        std::cout << a[i] << " ";
    }
    std::cout << std::endl << "--------" << std::endl;
    a[3] = 4;
    for (int i = 0; i < 4; ++i) {
        std::cout << a[i] << " ";
    }
    std::cout << std::endl;
}

int main() {
    test();
    std::cout << std::endl;
    test();
}
