i've been thinking about writing a base conversion program and i need a little help. this program will have 2 inputs and 1 output. the first input is the concern. it will ask the question of which base you want to convert from and convert to. how should i implement this question? should the inputs be the actual base? for example: you want to convert from base 16 to base 10 do you input F,10 or 16,10? which would be easier? this question needs answered before i can go ahead with the program because computers treat numbers and letters differently. for the curious: the maximum base size would be 255 but the first 31 ascii codes are control codes and can't be used. ascii codes 132 and greater can't be input by the keyboard. that leaves about 120 for max base size. i've decides to use 63 as max base size because of ease of use. bases will start at 2 and use all the digits, then all uppercase letters, then all lower case letters. i can get bigger base sizes (most likely unlimited) but the output will not decode into single characters.
