C++ Naming Style

[qingquan-li]

1. Common C++ Naming Conventions

https://github.com/cpp-best-practices/cppbestpractices/blob/master/03-Style.md

• Projects and Files start with upper case (UpperCamelCase / PascalCase):

  MyProject
  

  HelloWorld.cpp
  

• Types start with upper case (UpperCamelCase / PascalCase):

  MyClass
  

• Functions and variables start with lower case (lowerCamelCase):

  myMethod()
  

  string userName;
  

• Constants are all upper case:

  const double PI = 3.14159265358979323;
  const double EULER_NUMBER = 2.71828；

• File Names

  Filenames should be all lowercase and can include underscores (_) or dashes (-), prefer "_".

  my_useful_class.cpp
  

• Type Names

  Type names start with a capital letter and have a capital letter for each new word, with no underscores.

  MyExcitingClass
  

• Variable Names

  The names of variables (including function parameters) and data members are all lowercase, with underscores between words.

  string table_name;
  

• Function Names

  Ordinarily, functions should start with a capital letter and have a capital letter for each new word.
