Program 1: Write a C program that reads A as 100 decimal (0x64) and calculate B so that A xor B = 120 (how do you show A B in C program?).
Program 2: Write a C program that sends values of -20 to +20 excluding 0 to Port B (there are 40 such values from -20, -19, .., -1, +1, =2,.. , until +20). You can use array, but are not limited to use an array.

PLEASE ensure it compiles and write the full program to receive full credit. Thank you so much for your help.
