 NAME

   max  - Find and return 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 comparison function
   that can be used in place	of the default operator<.  This
   function can be	used with all the datatypes	provided by
   the	standard library.

   max returns the first	argument when the arguments are	equal.

 EXAMPLE

   //
   // max.cpp
   //
    #include <algorithm>
    #include <iostream.h>
    #include <iostream.h>

   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;
    }

   Output :
   10 20	20 20
