Exercise: Selector with list of items from a file
- Write a program that will get a file on the command line.
- It will display a menu allowing the user to select item by selecting the number next to it.
- e.g. the file looks like this:
blue yellow green black
The menu should look like this:
1) blue 2) yellow 3) green 4) black
- The user then can select a number (e.g. 3) and the program prints "green".
- Make sure the program handles well if the input is invalid.
