2. Write an application that asks the user for a number. Print that number that many times (e.g., if the user gives the number 4, your program would print 4 four times).

3. Create a countdown. Write a program that counts down from 10 to 1. When your application reaches 1, print Blast off!

4. Create an adding machine. Ask the user to enter an unknown number of numbers (one at a time). Stop collecting numbers when the user enters 0. Report the count, sum and average.

5. Create a multiplication table. Prompt the user for a number and output the multiplication table (from 1 to 10) for that number.
