Exercise: Age limit
- Create a script called age_limit_stdin.cr
- Ask the user what is their age.
- If it is above 18, tell them they can legally drink alcohol.
- If is is above 21, tell them they can also legally drink in the USA.
- Extra: ask the user for their age and the name of their country and tell them if they can legally drink alcohol.
- See the Legal drinking age list.
- Don't worry if this seems to be too difficult to solve in a nice way. We'll learn more tools to improve.
