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
