Type long long initializing problem

Question

Can't use type long long at all, cause it works like an int. Is long long type has 4 bytes instead of 8?

Answer 1

You can check with sizeof(long long).

Answer 2

%d is to print a signed decimal integer. Use %ll instead (lowercase L).

Answer 3

@zen,
I checked already and it has 8 bytes. But it still works like 4 byte cause when i initialize
Long long a=2147483648;
Printf("%d",a);
the output is -2147483648
Any ideas?

Answer 4

Tried ("%ll",a) and now my output is empty.
