General min and max - C++

Question

Writing a general minimum function, Two questions came to my mind. The code works fine with any input type and different argument number:

namespace xyz
{

te         


        

Answer 1

After the answer and worth comments I did it as below:

template 
auto min(const T1 &a, const T2 &b) 
-> typename std::common_type::type
{
    return a < b ? a : b;
}

template 
auto min(const T1 &a, const T2 &b, const Args& ... args)
-> typename std::common_type::type
{
    return min(min(a, b), args...);
}
