Auto variable initialization

cnickp · 11-07-2009, 06:58 AM

I was experimenting in auto-variable initialization (eg int k; ) and I found out that :

--On most windows machines ints are not auto-initialized to 0
but
on some linux machines ints are auto-initialized to 0.

Is there any standard (C89 / C99?) which specifies the behavior of the following program or it is undefined?

Code:

int main (){
 int k;
 printf("%d",k);
}

Thanks in advance.

It is defined that they are not required to be initialized.
