Difference between C 8 bit 16-bit 32-bit compilers -


this question may redundant, didn't found exact answer.

what difference between c 8 bit 16-bit 32-bit compilers.

how .exe differ generated different compilers same code...........

16 bit compilers compile program 16-bit machine code run on computer 16-bit processor. 16-bit machine code run on 32-bit processor, 32-bit machine code not run on 16-bit processor. 32-bit machine code faster 16-bit machine code.

with 16 bit compiler type-sizes (in bits) following: 

short, int: 16  long: 32  long long: (no such type)  pointer: 16/32 (but 32 means 1mb address-space on 8086)

with 32 bit compiler object-sizes (in bits) following: 

short: 16  int, long: 32  long long: 64  pointer: 32

with 64 bit compiler object-sizes (in bits) following: 

short: 16  int: 32  long: 32 or 64 (!)  long long: 64  pointer: 64

[while above values correct, may vary specific operating systems. please check compiler's documentation default sizes of standard types]

following can explain little bit more... http://cboard.cprogramming.com/c-programming/96536-16-bit-compilar-32-bit-compilar.html
