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；

2. Google C++ Style Guide

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.
```
DeleteUrl()
```
