so right now i am reading in four characters at a time from my input file. my problem happens when there is only one character to read. I need to initialize these other three characters so they don't print out anything, but right now they are initializing to hex values "-52," each one of them. I tried making them zero, but i don't think that's what i want, because it still is printing out zeros in the hex editor. is there a way to initialize these characters so they don't print anything, zeroes or otherwise?
