Convert hex numbers from unsigned char to string

Question

I have an array of unsigned chars with hex values and I need to make a string of them. So when I have arr[0]=2b and arr[1]=fc I want to be able to make a string s="2bfc", not the characters from ascii codes. How can I do that?

`0x2B12` is too large to be an `unsigned char` which is one byte or `0-255` in decimal or `0-FF` in hex. Your welcome. — marshal craft, Jan 15 '17 at 14:18

You could change to long or int and loop through adding +arr[ArrayIndex]*0x10^ArrayIndex to get one int representation of it using itoa(), then convert the int to a literal string of it. Just to outline a manual process of doing it.

You can do exponentiation however you like. – marshal craft Jan 15 '17 at 14:35
