Create a variable called studentAge and give it a value between 6 and 19.

Write code that does the following, using an if..else if statement.

• if studentAge is between (and including) 6 and 13, log "Barneskole"
• if studentAge is between 14 and 16, log "Ungdomsskole"
• if studentAge is between 17 and 19, log "Videregående skole"
