I need to write a program that counts in Hex to an unsecified number and writes to a file the number it is on when it counts, but I need it to skip 3 and 6.
I am confused as hell I cannot find such a thing in any of the books I have gotten.
Could someone help me and also recomend a good C book that is easy enough for an intermediate person to learn(all the books I find are either for beginer or advanced).
Thank you.
