+Write a **program** that prints the corresponding letter in the `n` position of the classic latin 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 (" ").
+For example `1` matches `a`, `2` matches `b`, etc. If `n` does not match 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. 
+A flag `--upper` should be implemented. When used the program prints the result in upper case.
