    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)

    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);
}

    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
