Transcribed Image Text:3. Grade is an unsigned byte stored in the program memory (PM). Letter is a byte stored in the data
memory. Letter = "A", "B", "C", "D", or "F" based on the value in Letter.
(89 < A; 79 < B < 90; 69 < C < 80; 59 <D < 60; F < 60)
4. Hex_ascii is an unsigned ASCII byte that can be one the following values: '0", '1', '2', '3', '4', '5', '6', '7',
'8', '9', 'A', 'B', 'C', 'D', 'E', 'F'. Note that '0'-'9' = 0x30-0x39 and 'A'-'F' = 0x41-0x46. Write a program that
will convert Hex_ascii from ASCII to a number (0-15) and store it in digit. Hint: simply subtract 0x30 for
ASCII '0'-'9', and subtract 0x37 for ASCII 'A'-'F".
