Once you finish: Basic Input/Output, try making some unit converters:
1. Have a program prompt you for a number in feet and then output the result in meters.
2. Have a program prompt you for Degrees in Celsius and then output the result in Fahrenheit.
3. Have a program prompt you for the a, b, and c, coefficients for the quadratic equation and then output the two answers.
Once you finish the module on Control Structures, you'll be able to do a little more.
