How can I store and/or print() a number that is larger than 4 294 967 295 in C? is int64_t or u_int64_t what I need ? if, so how can I printf it to stdout?

On HP-UX, this program works:

#include<stdlib.h>
#include<stdio.h>
main()
{
         long i;
         i=5000000000;
         printf("i = %ld \n", i);
          exit (0);
}

To get this to work I had to specify the +DD64 option on the cc command. HP's compiler defaults to 32 bit mode.

I wasn't sure is this was HP-UX specific, there is a weirdicious feature in GCC that will make the aforementioned program work with two changes (at least under Linux)

Use data type

long long l; /* Not typo! will compile */

and printf("%Ld", l); /* Notice capital L */

If GCC is used on various Os'es, it should work.
(I just checked on Solaris, it prints 1 :frowning:
