1. Write a program that sets a variable age to 15. Then check this age to see if I am under 18, and if I am, tell me "You are not old enough to see the movie."
   


2. Write a program that sets a variable cost to 20.00, as follows: cost = 20.00;. This will represent $20. Now check if the cost is less than $30. If it is, say "Bargain", if not, say "Ripoff"
   


3. Write a program that reads an integer variable named sticks from the user, using sticks = parseInt(prompt("Enter sticks: "));. If I have at least 7 sticks in Minecraft, I can craft a wooden ladder. If I can craft a wooden ladder, say "You can craft a wooden ladder." Otherwise don't say anything.
   


4. Write a program that checks students age at a student disco. If the student is aged 18 or over, they are not invited into the disco. Let them know.
   


5. Write a program that tells me whether a number is positive or negative (i.e. less than 0).
   


6. Add another choice to the nested / age program, so that if I am between the age of 45 and 65, the program should say Become a manager.
