For my programming class, I have to make a app that converts whatever base into whatever else base. Not hard. At all. The only thing I'm wrestling over before I start actually coding is how I should use arrays. I was just going to make a string and store each new 0-9 or A-Z character in there. Do you think he's wanting us to use an array to store the result? I was thinking more along the lines of having an array that holds the characters A-Z for numbers 10-36 and having the function access that array and then return the appropriate character by a value passed to that function. So.. what do you guys think?
