Answer 4

To clarify, no one programs in Hex.  Hex generally is a display of binary information using 16 digits (0-9 and A-F as opposed to decimal using 10 digits, 0-9 and binary using 2 digits, 0-1) usually in pairs of four bits each (1 byte), i.e. FF would be 11111111 in binary or 255 in decimal.  You can use windows calculator in scientific mode to convert decimal, binary and hexadecimal (hex) if you like.  

He may be talking about writing in machine language.  Few people do that anymore.  The reason is that you can get the same effect by writing in C++ (or any other compiled language) and then compiling.  The compiler converts your program to computer language which is stored binary and can be read to an extent with a Hex editor.

ASCII is a conversion of each byte value into a recognizable (or useful) symbol.  It's used a lot when storing or transferring text files.  Here's a table of that conversion (there's a ton out there):
