Output of the Program | Use Macros Carefully!
Predict the output of the below program
Preprocessor replaces square(6) by 6*6 and the expression becomes x = 36/6*6 and value of x is calculated as 36. If we want correct behavior from macro square(x), we should declare it as
#define square(x) ((x)*(x)) /* Note that the expression
(x*x) will also fail for square(6-2) */
