## Exercises: Functions

These exercises are based on the variables exercises, so you may start from those (your solutions or ours) or start from scratch.

Why pay a fortune teller when you can just program your fortune yourself?

• Write a function named `tellFortune` that:
• takes 4 arguments: number of children, partner's name, geographic location, job title.
• outputs your fortune to the screen like so: "You will be a X in Y, and married to Z with N kids."
• Call that function 3 times with 3 different values for the arguments.

Forgot how old you are? Calculate it!

• Write a function named `calculateAge` that:
• takes 2 arguments: birth year, current year.
• calculates the 2 possible ages based on those years.
• outputs the result to the screen like so: "You are either NN or NN"
• Call the function three times with different sets of values.
• Bonus: Figure out how to get the current year in JavaScript instead of passing it in.

Ever wonder how much a "lifetime supply" of your favorite snack is? Wonder no more!

• Write a function named `calculateSupply` that:
• takes 2 arguments: age, amount per day.
• calculates the amount consumed for rest of the life (based on a constant max age).
• outputs the result to the screen like so: "You will need NN to last you until the ripe old age of X"
• Call that function three times, passing in different values each time.
• Bonus: Accept floating point values for amount per day, and round the result to a round number.
