int main() 
    { 
    Myarray c0 = {0, 1, 2, 3}; 
 
// display contents " 0 1 2 3" 
    for (Myarray::const_iterator it = c0.begin(); 
        it != c0.end(); ++it) 
        std::cout << " " << *it; 
    std::cout << std::endl; 
 
    Myarray c1 = {4, 5, 6, 7}; 
    c0.swap(c1); 
 
// display swapped contents " 4 5 6 7" 
    for (Myarray::const_iterator it = c0.begin(); 
        it != c0.end(); ++it) 
        std::cout << " " << *it; 
    std::cout << std::endl;
