template <typename T>
inline T const& max (T const& a, T const& b)
{
return a < b ? b : a;
}
int main()
{
max<double>(1.0, -3.0); // explicitly specify template argument
max(1.0, -3.0); // template argument is implicitly deduced
// to be double
max<int>(1.0, 3.0); // the explicit <int> inhibits the deduction;
// hence the result has type int
}
