milenko Thanks for the explanation. But I still don't understand why the linker complain when I define variable as following: mya.c myb.c error occurs? ----------------------------------------------------- int tv; int tv; No int tv=10...

Much thanks for those reponses! I know using extern could eliminate the error. But what I really want to know is: in what way the linker treat the same global variables defined in two different files. I also did the following test: 1) using Unix gcc mya.c myb.c error...

Hi Gurus, I got confused about a C global variable question. There are 3 very simple C files: mya.c --------------------- #include <stdio.h> int tv=10; printav() { printf(&quot;&av= %x\tav = %d\n&quot;, &tv, tv); } ------------------------ myb.c ------------------------ #include...

I agree with what Ankan's said. &quot;name&quot; is the variable name of an array. So &quot;&name&quot; is valued as the address of this variable, it's equivalent to &quot;&name[0]&quot;. Things would be different if the variable is defined as: char * name = &quot;scott&quot; This time...

I was confused about such a fact: when I declare a array of char type like the following: char name[30]=&quot;scott&quot;; then I have a printf statement: printf(&quot;Addr: %x\n&Addr: %x\n&quot;, name, &name); I got the same value of these two address. who can tell me the reason about...
