If you include the standard I/O library, C is Turing complete.However, freestanding C without the standard library is only PDA-complete.
>>107600585Turing complete means infinite RAM.

>>107600749No halting program uses infinite RAM, so a device that executes all the stuff you need without running out is a Turing Machine
>>107601129malloc((size_t) (1.0f / 0.0f));
malloc((size_t) (1.0f / 0.0f));
>>107600749It means being able to simulate an infinite tape, regardless of the actual mechanism involved (RAM, I/O). Hence, using files is not "cheating".
