};
  
template<typename T, size_t pair_size> void printPairs(T const(& pair)[pair_size]) {
    for (int i = 0; i < pair_size; i++) {
        std::cout << "{" << std::to_string(pair[i].x) << ", " << std::to_string(pair[i].y) << "}" << "\n";
    }
}
  
int main()
{
    Pair pair[] = { {7, 2}, {1, 8}, {5, 9}, {9, 3}, {2, 7}, {1, 5}, {4, 6} };
     
    printPairs(pair);
