Provide a brief definition of the following terms (in the interface programming context):

• Array
• Array index
• Array element
• Sort an array

Roulette.exe

• Design a form like that above.
• Using a NumericUpDown control the user enters a number of dollars to start with.
• A spin of the roulette wheel is simulating using a random number generator draw a number between 1 and 38. The numbers 1 through 36 are themselves and 37 and 38 correspond to 0 and 00.
• According to http://en.wikipedia.org/wiki/Roulette {1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36} are Red; {2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35} are Black; and 0 and 00 are Green.
• Assuming the player bets on Red, determine if the player has won or lost a dollar and adjust the player's amount. (I used a Select Case because it will accept a comma-separated list.)
• The player continues to bet while he/she has money. Count the number of spins of the wheel needed for the player to lose his/her money.
• Place the above in a loop that repeats the simulation process the number of times requested by the user. (Don't forget to reset the player's amount and the spin counter.)
• Keep a history of the number of spins needed in a ListBox.
• Calculate the average number of spins.
• Clear out the results if the user changes any input.
• Make sure the user enters a number for the sample size.

  The Scream

  Scream.exe
  • Design a form with an image in which the image grows and shrinks. The image I used is The Scream by Edvard Munch, but you can use a different image.
  • Use a timer to change the PictureBox's width and height. In order to maintain the aspect ratio (to some extent), the image width and height of the example were multiplied by a number such as 1.03 to grow and 1/1.03 to shrink.
  • To keep the image centered the X component of the PictureBox's location was set to half of the form's width minus half of the PictureBox's width. It is somewhat similar for the Y component (though you may have to adjust for the Form's title bar.)
  • Experiment with conditions for switching from growing to shrinking and back again.
  • (In the example, the PictureBox is always larger than the form.)
