Declaration


  
#include <algorithm>

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

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

Complexity

Time and space complexity are constant.

Example <ospace/osstd/examples/max1.cpp>


    #include <iostream>
#include <algorithm>

void
main()
  {
  cout << max( 42, 100 ) << "\n";
  }

100

Example <ospace/osstd/examples/max2.cpp>


    #include <iostream>
#include <string.h>
#include <algorithm>

bool
str_compare( const char* a_, const char* b_ )
  {
  return ::strcmp( a_, b_ ) < 0 ? 1 : 0;
  }

void
main()
  {
  cout << max( "shoe", "shine", str_compare ) << "\n";
  }

shoe
