Why the following function is called thrice

Question

I had tried to debug but no luck I can\'t understand why the second printf() is call increment() thrice but the first one call twice as expected.

#include &l         


        

Answer 1

Because you tell it so:

MAX(x, increment())

evaluates to

( (x) > (increment()) ? (x) : (increment()) )

and if the condition is not fulfilled, the part after the : is evaluated and thus the function called again.
