Architecture 64 Bit Vs 32. In the context of a processor, the number of bits generally refers to the amount of memory it can address. It solely depends on the abi of the platform.
32 Bit vs 64 Bit Operating Systems What's the Difference? from www.hitechwork.com
Sizeof(int) with some of the more common compilers may give you 4 for a 32 bit platform and 8 for a 64 bit platform but this is not guaranteed. It solely depends on the abi of the platform. Linux firefly 4.4.114 #62 smp wed apr 4 11:10:34.
It Is Equal To 4 Gb (Gigabytes) Of.
On some 32 bit architectures, 64 bit alignment can be used, e.g. A safe and portable technique is unfortunately impossible (because safe and portable only allows you the rules in the c standard). It solely depends on the abi of the platform.

All the c standard says is that an int should be the 'natural' size for calculations on. Sizeof(int) with some of the more common compilers may give you 4 for a 32 bit platform and 8 for a 64 bit platform but this is not guaranteed. If i choose 64 bit software, wrong architecture if i choose 32 bit software, wrong architecture.
There Is A Clear Difference Between The Two Types Of Processor Architectures And This Becomes Evident With The Software That Can Run On Each Architecture.
In the context of a processor, the number of bits generally refers to the amount of memory it can address. The x86 (32 bit processors) has a limited amount of maximum physical memory at 4 gb, while x64 (64 bit processors) can handle 8, 16 and some even 32gb physical memory. Your question is too broad.
The C Standard Does Not Enforce Any Kind Of Alignment.
