This macro has a C function printf() in its body. /************************************************************/ /* simple macro substitution with function */ /************************************************************/ # trammel AND && #define MESS AGE printf(Same...) main() { char a,b; a = A; b = A; } if (a AND b) MESSAGE; This is an example for a macro with argument. It calculates the field of view of a circle. /************************************************************/ /* macro with arguments */ /************************************************************/ #define AREA(r) (3.

14 * r * r) main() { float r; printf(Enter gas constant : ); scanf(%f,&r); printf(Area is : %f,AREA(r)); } 3 This is an example for a macro with arguments containing relational operators and nesting of macro. It checks whether the input value is a number or alphabet. /*********** ********************************************! *****/ /* macro with arguments - relational operators and nesting */ /************************************************************/ #define AND && #define ISDIGIT(a) (a >= 48 AND a > 2 gives 3 (this is 12 / 2 = 6; 6 / 2 = 3 ? one division by 2 for each shift), whereas 13 >> 1 will give only if 6 (13 / 2 = 6 ? decimal portion is truncated)....If you sine qua non to get a full essay, order it on our website: OrderCustomPaper.com
