Now you get 1, then 1, then 1#include <stdio.h> Ehm, why do you think that will happen?void foo(void){ Because you said they where initialized to 0 int a; ++a; But this is not a static variable printf("%dn", a);} ah, then you get three garbage valuesint main(void) the value of a will be undefinded, so in theory you{ get three garbage values. In practice however, since foo(); auto variables are often allocated on an execution foo(); stack, a might get the same memory location each foo(); time and you might get three consecutive values... if} you compile without optimization. on my machine I actually get, 1, then 2, then 3 I am not surprised... if you compile in debug mode the runtime might try to be helpful and memset your stack memory to 0
