Something I’ve used in the past:

int hex2Bin(char c)
{
int bin = 0, ten = 1, i;
for (i = 0; i < 8; i++)
{
bin += ((c & (0×1 < 0×0) ? ten : 0;
ten *= 10;
}
return bin;
}

…

printf(“%08d”, hex2Bin(c));

Oh yeah, for those of you who think that this is the best way of doing things, here’s a hint:

printf(“0x%02x”,c);

Not every solution fits the same problem.
