What to Do?

1. Work through Part 3 - Keyboard Input tutorial

   1. • Make a project that you can experiment with as you do the readings

      • You will need to be able to convert data stored as a string to various numeric formats:

        • • Use the Convert class for a wide range of conversions

            • https://docs.microsoft.com/en-us/dotnet/api/system.convert?view=netframework-4.8

          • Use the TryParse() method in Double and Int32 for built-in error proofing.

            • https://learn.microsoft.com/en-us/dotnet/api/system.int32.tryparse?view=net-8.0

      • Complete the User Input Programming Assignment (Greetings, Adder, Distance, Hypotenuse).

        • • These will be handed in.

          • It is a good skill to get used to reading through the official documentation provided by Microsoft in order to help you use various libraries in C#.  Here is a link to the Math Class library.  Have a look at the Methods section to see what other methods are available:

            • • https://docs.microsoft.com/en-us/dotnet/api/system.math?view=net-6.0

          • You will need the Sqrt() and Round() methods.  See if you can figure out how to use them from the documentation.  The Pow() method may also be useful.

            • • Sometimes the examples are overly complicated and not helpful.  If this is the case, look elsewhere on the internet.

SUBMIT

• • A project Part 3 - Console Input consisting of 4 parts:

    • 1. Greetings

         • • Optional bonus using system date.

      2. Adder

      3. Distance

      4. Hypotenuse

  • Feel free to augment your assignment with colors and other console features:

Q: My program crashes when I try to convert a non-numeric value.  How can I fix this?

A: In Part 5 we cover error checking by using TryParse() to convert instead of the Convert class.  You are welcome to read ahead if you wish or use the internet to help you.
