Is that integer size would be differ for every 16bit, 32bit controller??

Is that integer size would be differ for every 16bit, 32bit controller?

Int   x;

Is that now x will occupy different size in 16 bit,32 bit ??

Then what about the short int, long int,double, — All vary on architecture of controller ??

If we need to perform some 32 bit operations in 16 bit controller, how to do ??

i think int take a single word size of the controller(if 8 bit — 8, 16 bit — 16 bit), 

I am so confused. kindly answer me with clear data(if possible example)

 

Thanks in Advance

Gokul

Hi,

Integers are your primary data-type for number storage.

On the Arduino Uno (and other ATMega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) – 1).
On the Arduino Due and SAMD based boards, an int stores a 32-bit (4-byte) value. This yields a range of -2,147,483,648 to 2,147,483,647 (minimum value of -2^31 and a maximum value of (2^31) – 1).

it depends upon which cross compiler tool you are using

in normal C language int means 2 byte of memory

in all the controllers int type variable has 16 bit only
