What's the side effect of the following macro in C ? Embedded C

Question

#define MIN(A,B) ((A) <=  (B) ? (A) : (B))

this is the macro , I was asked what\'s the side effect if I used the following :

lea         


        

Answer 1

The macro will expand to:

least = ((*p++)<=(b)?(*p++):(b))

you will have then *p++ twice in your statement (i.e., it will be incremented twice).
