C# Code wanted.

1. create a 2x2 matrix program.  Test it and  take screen captures to show all four possibilities are accounted for.
2. Using a loop write a conversion program that will use the  MessageBox to display at least 5 different conversions between inches  and centimeters or some other conversion.  The program should have a  start button and when it is clicked the conversions should be displayed  one at a time.   You can pick the start and the increment but it should  loop at least 5 times.  Example output for one loop iteration:  1  inch(es) = 2.54 cm .  Clicking the OK in the MessageBox will display the  next conversion: 2 inch(es) = 5.08 cms .  Etc. up until the 5th  iteration.
