{
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;
swap(c0, c1);
// display swapped contents " 0 1 2 3"
for (Myarray::const_iterator it = c0.begin();
