C: array in global and inside funtion

+2 votes
#include <stdio.h>
char buff[10];

   char buff1[10];
   int i = 10;
   while(i-- > 0 ) 
      printf("%d %d\n", buff[i], buff1[i] );   

Here, buff will display all zeros where as buff1 through garbage values. How ?

Global variables are initialized to zero while local are not so you see buff is all zero and buff1 is all garbage.

how about the storage for buff1 ? is it in stack segment ?
Yes that is correct, local variables(non static) would be stored in the stack of the function.

I have a recursive function as below,

void func()

Here, I need to come out of the function when counter reaches specific number(10 as per example).
Now, the condition is, I can't take this counter as global or static or can't pass this counter as parameter.

Any suggestion to solve this given above terms.
