Let DOUBLE be the following macro: define DOUBLE (x) 2 * x a) What is the value of DOUBLE (1 + 2)? b) What is the value of 4/DOUBLE (2)? c) Fix the definition of double. For each of the following macros, give an example that illustrates a problem with the macro and show how to fix it. a) # define AVG (x, y) (x + y)/2 b) # define AREA (x, y) (x) + (y)

Explanation / Answer

1(a) #define TRUE 1

(b) #define FALSE 0

(c)#ifdef YES
#undef YES
#define YES 1

d)  #define Area(x) x*x

e)  #define Sum(x, y) x + y
