dos and don'ts of writing c++ code

1. Use namespaces - when you have huge code and classes, add them into a name spaces by categorizing them. Like a namespace for database, namespace for logger, namespace for ui etc.

3. In header files, avoid the use of forward declaration as much as possible and included the required header files.
