    a, b -
    die zu vergleichenden Werte
    Original:

    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)

    [Bearbeiten]Mögliche Implementierung

    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);}

    [Bearbeiten]Beispiel

    #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';}

    Output: 

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