  1. Ten Bouncing Balls Presented by Quentin Ochem university.adacore.com

  2. {X, Y} {X’ = X + Dx Y’ = Y + Dy}

  3. Checks if a value is within an range

  4. Moves using a vector

  5. Get access to random functions

  6. Initializes a generator to the default

  7. Value in [0.0 .. 1.0]

  8. Value in [0.0 .. 0.05]

  9. Value in [0.02 .. 0.07]

  10. Value in [0.02 .. 0.07] Value in [0.0 .. 1.0]

  11. Value in [0.02 .. 0.07] Value in {-1.0, 1.0}

  12. Value in {[-0.07 .. -0.02], [0.02 .. 0.07]}

  13. Declares an array type

  14. The array in indexed by Integer

  15. The array contains a number of elements to be specified at declaration

  16. The array contains instances of Ball_Type

  17. Declare an array of type Ball_Array

  18. Gives boundaries between 1 and 10 (10 elements)

  19. Initializes the array through an aggreate

  20. Every value is initialized through the same expression

  21. Initializes each component through the same record aggregate

  22. These will be recomputed for each element!

  23. Iterate through each element of Balls

  24. Identify the Errors

  25. “range <>” needs to bespecified for an unconstrained array

  26. “others =>” is missing to specifythat a value is givento all objects

  27. “of” is the notationto iterate over theelements
