NAME
     max

      - Finds and returns the maximum of a pair of values.



SYNOPSIS
     #include <algorithm>
     template <class T>
     const T& max(const T&, const T&);

     template <class T, class Compare>
     const T& max(const T&, const T&, Compare);



DESCRIPTION
     The_max algorithm determines and returns the  maximum  of  a
     pair of values. The optional argument Compare defines a com-
     parison function that can be used in place  of  the  default
     operator<.

     max returns the first argument when the arguments are equal.



EXAMPLE
     //
     // max.cpp
     //
      #include <algorithm>
      #include <iostream>
      #include <iostream>
     using namespace std;

     int main(void)
      {
       double d1 = 10.0, d2 = 20.0;

        // Find minimum
       double val1 = min(d1, d2);
        // val1 = 10.0

        // the greater comparator returns the greater of the
        // two values.
       double val2 = min(d1, d2, greater<double>());
        // val2 = 20.0;

        // Find maximum
       double val3 = max(d1, d2);
        // val3 = 20.0;

        // the less comparator returns the smaller of
        // the two values.
        // Note that, like every comparison in the STL, max is
        // defined in terms of the < operator, so using less here
        // is the same as using the max algorithm with a default
        // comparator.
       double val4 = max(d1, d2, less<double>());
        // val4 = 20

       cout << val1 << " " << val2 << " "
             << val3 << " " << val4 << endl;

       return 0;
      }

     Program Output



     10 20 20 20
