compiler

if compiler is 16 bit compiler then int is of 2 bytes (turbo c)
if compiler is 32 bit then int is of 4 bytes in VC++

but for 32 bit compiler processor should be compatible i.e. of 32 bytes
so processor also decides it
again of OS
if os is 16 bit how you r going to run a 32 bit compiler on it

so a confusing question
