  12. Data structures

  13. Data structures • Data structures are the tools of the computer science trade.

  14. Data structures • Data structures are the tools of the computer science trade. • They provide ways to organize data in the computer's memory.

  15. Data structures • Data structures are the tools of the computer science trade. • They provide ways to organize data in the computer's memory. • … in order to give the data _______.

  16. Data structures • Data structures are the tools of the computer science trade. • They provide ways to organize data in the computer's memory. • … in order to give the data _______. Wait for it

  17. Data structures • Data structures are the tools of the computer science trade. • They provide ways to organize data in the computer's memory. • … in order to give the data structure.

  18. Array

  19. Array • This is a linear group of adjacent containers.

  20. Array • This is a linear group of adjacent containers. • Each container can store one thing.

  21. Array • This is a linear group of adjacent containers. • Each container can store one thing. • Containers can be accessed randomly.

  22. Array • This is a linear group of adjacent containers. • Each container can store one thing. • Containers can be accessed randomly. • This is known as a random access data structure.

  23. Array • This is a linear group of adjacent containers. • Each container can store one thing. • Containers can be accessed randomly. • This is known as a random access data structure. • An array's size can't be increased after it's been created. Need to create a new array instead.

  29. Array 1 2 3 4 5 6 7 You know where the beginning is and you know how wide each box (container) is, so you can easily find any other box.

  30. Array Where is the beginning of box 4? 1 2 3 4 5 6 7

  31. Array Where is the beginning of box 4? 1 2 3 4 5 6 7

  32. Array Where is the beginning of box 4? 1 2 3 4 5 6 7 x 3

  33. Array Where is the beginning of box 4? 1 2 3 4 5 6 7 x 3 =

  34. Array Where is the beginning of box 4? 1 2 3 4 5 6 7 x 3 =

  39. Linked list

  40. Linked list • This is a linear group of non-adjacent containers.

  41. Linked list • This is a linear group of non-adjacent containers. • Each container can store one thing.

  42. Linked list • This is a linear group of non-adjacent containers. • Each container can store one thing. • Containers can not be accessed randomly.

  43. Linked list • This is a linear group of non-adjacent containers. • Each container can store one thing. • Containers can not be accessed randomly. • Start at first container, move down the list one container at a time to find the one you want.

  44. Linked list • This is a linear group of non-adjacent containers. • Each container can store one thing. • Containers can not be accessed randomly. • Start at first container, move down the list one container at a time to find the one you want. • Easy to add or remove containers.
