The reason for merging the two programs (cmd and inter) is for code
maintainability. Basically the two programs should be exactly the same
except for how they process user input. This difference in input
processing should be done as separate functions, not as separate
programs. All that is needed is a simple check for command line
arguments and you call the function that processes the arguments if they
exist. If there are no arguments, then you call the function that
prompts the user for the input.

This way, if you want to change the program, you only need to change one
program, not two. Thus, the code is easier to maintain.
