Instructions
Write a program that prints the corresponding letter in the n position of the alphabet, where n is each argument received.
For example 1 is a, 2 is b, etc. If n is not a valid position of the alphabet or if the argument is not an integer, the program should print a space (" ").
It should be implemented a flag --upper that prints the result in upper case.
