Development of a computer program

• Modelling diagrams

  • Use case diagrams, illustrates systems functionalitites from the user's perspective.
  • Context diagrams, provide a high-level view of the system and its environment.
  • Data flow digrams, show how data moves through the system and is processed.
• Control Structures

  • Sequence, a set of instructions thatt executes line by line
  • Conditional, runs a section of code when a requirement is met
  • Iteration, used to repeat sections of code multiple times
• Searching and Sorting algorithms

  • Selection sort, involves searching through a whole list and selecting a value and swapping to the front of the list
  • Quicksort, works by dividing a list into smaller parts and sorting it. Uses a pivot which is used to divide list
  • Linear search, searching every element in the list for the item
  • Binary search, searches through sorted data by dividing the list into smaller parts
