Answer 1

Assuming that this is a homework, here's a couple of hints:

• The value in the variable is not in decimal, hex, or any other system: it is in whatever system that your hardware supports (most likely, it is binary).
• To convert a value to hex, you need to separate out 4-bit chunks by shifting right and masking with 0x0F, and indexing into an array of hexadecimal digits.
