Nit: ints are still 32 bits on most 64-bit systems ( http://en.wikipedia.org/wiki/64-bit#Specific_data_models http://en.wikipedia.org/wiki/64-bit#Specific_data_models )
Example:
mrj10@mjlap:~$ uname -m
x86_64
mrj10@mjlap:~$ cat test.c
#include <stdio.h>
int main()
{
printf("%zu\n",sizeof(int));
return 0;
}
mrj10@mjlap:~$ gcc test.c -o test
mrj10@mjlap:~$ ./test

- Groxx 17y agoHah, yep, does the same on mine. Oh well. Thanks for the info. Long int gives me 8, but I see that the standard only requires 4 minimum, so I guess you can't rely on that either... Eh. I'll still stick with infinite Integers if I'm worried about running out of space.
- jedbrown 17y ago> I see that the standard only requires 4 minimum Oh really? What standard? C99 section 5.2.4.2.1 says 16 bits minimum for int, 32 bits for long, 64 for long long. There may not exist 64-bit architectures with 16-byte ints, but that's not prevented by the standard.
