#include <iostream>
using namespace std;
   
inline int max(int a, int b)
{
  return a>b ? a : b;
}
   
int main()
{
  cout << max(10, 20);
  cout << " " << max(99, 88);
   
  return 0;
}

// As far as the compiler is concerned, the preceding program is equivalent to this one:
/*
#include <iostream>
using namespace std;
   
int main()
{
   
  cout << (10>20 ? 10 : 20);
  cout << " " << (99>88 ? 99 : 88);
   
  return 0;
}
