| Jun 23, 2017 at 1:14 | comment | added | Dinaiz | Sorry to say that but sizeof is evaluated at compile time. So if you compile a 32 bit exe and run it on a 64 bit machine, it will ouput 32 while it should output 64 (stackoverflow.com/questions/2615203/…). Nice idea though ! | |

| Jun 21, 2017 at 23:24 | comment | added | David Schwartz | This doesn't comply with the requirements. "Please note that a 32 bit program running on a computer with a 64 bit operating system should output "64"." This tells you how the program was compiled, not what the OS is. | |
| Jun 21, 2017 at 6:06 | comment | added | k_g | Since this only needs to work on some systems, can you just assign the result to a variable (so it's on top of the stack) instead of returning it? | |

it also won't work if CHAR_BIT != 8

@KenY-N, you're right; this returns 32 when compiled with the -mx32 option in gcc. x32 mode is only available on x86_64 processors.

| Jun 19, 2017 at 21:42 | comment | added | Dennis | It also says that the usual code golf rules apply, and returning from a function is part of our defaults for I/O. | |
| Jun 19, 2017 at 21:41 | comment | added | Govind Parmar | @Dennis the challenge specifically says"print" in the OP | |

No need for printf, you can simply return the integer.
