A quick review of C++

• About my notes:
  • They are for me, to remind me what to cover.
  • They will be available before class (mostly)
  • They might be more/less complete, depending on the topic.
  • We will probably depart from them quite a bit as we go.
• Basic Unix
  • make sure you can get to ~dbennett/230
  • ls
  • cp
  • mkdir
  • cd
  • mv
• What is C?
• What is C++?
• Basic program shell (write hello world)
• Compiling and basic Make.
• What is an identifier?
  • What are the rules for making them?
  • Where are they used?
  • What are the conventions for making them?
• 4 basic data types.
• Two (at least) complex data types
• How are these different.
• Constants
  • What are they?
  • Where are they declared
  • Conventions for use?
• Control structures
  • What are the basic control structures?

    • prints the number of numbers in the file.
    • Prints the sum
    • Prints the max/min
    • Prints the mean

  • What are local variables to a function?
  • What is the scope of a variable?
  • What is a global variable?
  • Why are functions good?
    • Breaks the problem down into smaller parts for easier coding.
    • Makes smaller sections of code for debugging.
    • Lets you think at a higher level.
    • Lets your reuse code.
    • Decreases code size.
    • Means you only debug the solution once.
    • Makes it easier to modify/extend the code.
  • Write a stick number to Arabic converter.
  • Write a comma delimited number to Arabic converter.
