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

The Age Calculator

Want to find out how old you'll be? Calculate it!

• Store your birth year in a variable.
• Store a future year in a variable.
• Calculate your 2 possible ages for that year based on the stored values.
• For example, if you were born in 1988, then in 2026 you'll be either 37 or 38, depending on what month it is in 2026.
• Output them to the screen like so: "I will be either NN or NN in YYYY", substituting the values.

• Calculate how many you would eat total for the rest of your life.
• Output the result to the screen like so: "You will need NN to last you until the ripe old age of X".
