Section 16.9: Generic Min/Max with variable argument count

Version > C++11

It's possible to write a generic function (for example min) which accepts various numerical types and arbitrary argument count by template meta-programming. This function declares a min for two arguments and recursively for more.

template <typename T1, typename T2> auto min(const T1 &a, const T2 &b)

-> typename std::common_type<const T1&, const T2&>::type

{

return a < b ? a : b;

}

template <typename T1, typename T2, typename ... Args> auto min(const T1 &a, const T2 &b, const Args& ... args)

-> typename std::common_type<const T1&, const T2&, const Args& ...>::type

{

return min(min(a, b), args...);

}

auto minimum = min(4, 5.8f, 3, 1.8, 3, 1.1, 9);
