Hey, I'm learning about the limits header, and I don't understand one
snippit of code. If I code:

#include <limits.h>
#include <stdio.h>
int main()
{
printf("Smallest signed long long: %lld\n", LLONG_MIN);
return 0;
}
I get the output:
Smallest signed long long: 0

Why is this? I even check in my limits.h file, where I see:
#define LLONG_MIN 0x8000000000000000 /*minimum signed __int64 value */

Why won't it print the limit?
 
printf("Smallest signed long long: %lld\n", LLONG_MIN);

Iam not sure, but what if you try %i64 as format specifier?

I'm learning about standard C and %i64 makes assumptions about long long
being 64 bit so that probably is not standard C.
I guess the latest VC has implemented long long as an afterthought.
