Not sure if this is hardware, software or compiler dependent


$ uname -a
CYGWIN_NT-5.1 machinename 1.7.28(0.271/5/3) 2014-02-09 21:06 i686 Cygwin

On a 32 bit XP SP 3 platform

wrote a small profram to check some parameters;
Received the following Re: Signed abd unsigned iintegers

[quote]
int x = 0xAB78 in decimal format is : 43896
and
unsigned int y = 0xAB78 in decimal format is : 43896
The  size of int is 4 bytes
[/quote]


Not quite what I expected, sine the leftmost bit in 'int' is 1 and
would be the negative flag.

So wrote another for byte sizes and got the following -

[quote]
The  size of short int is 2 bytes
The  size of int is 4 bytes
The  size of long int is 4 bytes
The  size of double is 8 bytes
The  size of long double is 12 bytes
[/quote]

Note size of int and long int are the same both are 4 bytes long

Is this to be expected?

Thanks!
