      cmp - comparison function which returns ​true if if a is less than b.

      The signature of the comparison function should be equivalent to the following:

       bool cmp(const Type1 &a, const Type2 &b);

      The signature does not need to have const&, but the function must not modify the objects passed to it.
      The types Type1 and Type2 must be such that an object of type T can be implicitly converted to both of them. ​

      Type requirements
      -
      T must meet the requirements of LessThanComparable. for the overloads (1) and (3)
      -
      T must meet the requirements of CopyConstructible. for the overloads (3) and (4)

      [modifier]Mise en œuvre possible

      First version 
      template<class T>const T& min(const T& a, const T& b){return(a < b)? a : b;}
      Second version 
      template<class T, class Compare>const T& min(const T& a, const T& b, Compare comp){return(comp(a, b))? a : b;}
      Third version 
      template<class T> T min(std::initializer_list<T> ilist){return*std::min_element(ilist.begin(), ilist.end());}
      Fourth version 
      template<class T, class Compare> T min(std::initializer_list<T> ilist, Compare comp){return*std::min_element(ilist.begin(), ilist.end(), comp);}

      [modifier]Exemple

      #include <algorithm>#include <iostream>   int main(){std::cout<<"smaller of 1 and 9999: "<< std::min(1, 9999)<<'\n';std::cout<<"smaller of 'a' and 'b': "<< std::min('a', 'b')<<'\n';std::cout<<"smaller of 3.5 and 2.5: "<< std::min(3.5, 2.5)<<'\n';}

      Résultat : 

      smaller of 1 and 9999: 1 smaller of 'a' and 'b': a smaller of 3.5 and 2.5: 2.5
