// // This version of MIN should not be used with expressions with side effects. // Don't try: min=MIN(x++,y++); // #define MIN(a,b) (((a) < (b)) ? (a) : (b)) // // Extra parentheses avoid possible precedence problems with things like // MIN(r>s?5:1,t>u?6:t) // Don't write ugly code like that. // In general it is far safer to write a function. //
