1. Write a program that inputs two numbers. Test if the first number is greater than (or less than) the second. What happens if you enter numbers that are equal? How do you account for the result?
2. Write a program that allows you to enter a numeric grade (i.e. 85, 68, 94). Output the corresponding letter grade. Be sure to test for all outcomes (i.e., 90, 80, 0, -1, 129). Display an error message where appropriate.
3. Write a program that takes as input the values 27.2, 35.6, 41.2. Compute the average of the three values.
4. Write a program that takes as input the month (1-12), day (1-31), and year (yyyy). Determine if the date entered is a valid birthday for someone who is alive today.
a.Check if the date is in the future (HINT: convert date to yyyymmdd format, i.e. 20140214 to test),
b. Check if more than 100 years old,
c.Check if days of the month are appropriate (i.e., February 31st is obviously wrong).
