This code is supposed to take diffrent inputs and create a file with
their outputs. The code takes an uppercase letter and turns it into a lowercase
letter. It then spits out the decimal, octal, and hex forms of the lowercase.
The code does the same with lowercase letters but turns them into uppercase
letters. the code also takes the ASCII decimal value and turns it into a 
character. Finally the code gives the valuse of any number from 1-32 to its
third power.*/
