Chapter 1 continues

• Since C++11, you can include ' in a number where we normally use commas

• const int BIG = 1'000'000; 

• You can also represent numbers in octal
  • Start with a 0, only have digits 0-7
• Binary
  • Start with 0b
  • only use digits 0 and 1
• And Hex
  • start with 0x and only use digits 0-9 and A-F
  • Apparently in C++17 you can also have hex floats 0x3.AF
• Look at the list of operators on page 13-14
  • As we saw with << we can overload ALL of these.
  • More on that later.
• Take a quick look at strong enumerated types
  • Listed on page 16

  • enum [class/struct] identifier [: integer type] { ENUMERATOR LIST};

  • Declares a new type

  • enum class ColorT: char {RED, GREEN, BLUE, NO_COLOR};

  • This is now a type.

  • enum class ColorT: char {RED, GREEN, BLUE, NO_COLOR};

    const ColorT FIRST_COLOR = static_cast(0) ColorT StringToColorT(string s); string ColorTToString(ColorT c); ColorT NextColorT(ColorT c);
