Не могу написать двоичный дамп для x86

const unsigned char bits[]={1,2,4,8,16,32,64,128};
const char nbits=8;

void dump(const void* pobject,int size)
{
int i,j;
for(i=0;i<size;i++) {
for(j=nbits-1;j>=0;j--) {
if(((char *)pobject)[j] & bits[j])
printf("%c",'1');
else
printf("%c",'0');
}
if(i<size-1)
printf("%c",'|');
}
printf("\n");
}

...

unsigned int i;
for(i=0;i<10;i++)
dump((void *)(&i),sizeof(i));

выдает:

00000000|00000000|00000000|00000000
00000001|00000001|00000001|00000001
00000000|00000000|00000000|00000000
00000001|00000001|00000001|00000001
00000000|00000000|00000000|00000000
00000001|00000001|00000001|00000001
00000000|00000000|00000000|00000000
00000001|00000001|00000001|00000001
00000000|00000000|00000000|00000000
00000001|00000001|00000001|00000001

Почему?
