There are two int variables: a and b, don’t use “if”, “? :”, “switch”or other judgement statements, find out the biggest one of the two numbers.

max.c

int max(int a,int b)  
{  
  return ( ( a + b ) + abs( a – b ) ) / 2;  
}  

max_min.c

int max(int a,int b)  
{  
  return *( &a + ((unsigned)(a - b) >> (sizeof(int) * 8 - 1)) );  
}  
  
int min(int a,int b)  
{  
  return *( &b - ((unsigned)(a -b )> > ( sizeof(int) * 8 - 1)) );  
}
