[HELP] C & long long

devo usare in un programma il tipo long long (int 64bit)
con gcc ma i risultati mi sembrano abbastanza bizzarri
can you help me?

include <stdio.h>
long long pow2=1;
int i;
int main ()

{
for (i=0;i<64;i++){
printf("2^%d=%llu \n",i,pow2);
pow2=pow2*2;}
return 0;
}

OK corretto da solo

printf("2^%d=%I64u \n",i,pow2);


qualcuno ha mai usato le GMP? fra un po devo passare agli interi
a 128bit
