Debugging is always pay important role in software development life cycle. You can make your life easy with the help of macros. With the help of macros you can enable and disable debugging and can define debugging level.
/**
* LOGGING LEVEL
* ***************
* Macro Reason
* ****************************************************************************************************************
* __DEBUG_LEVEL_LOG__ Complete logging including debug level, info level, warning level and error level
* __INFO_LEVEL_LOG__ Logging including info level, warning level and error level
* __WARNING_LEVEL_LOG__ Logging including warning level and error level
* __ERROR_LEVEL_LOG__ Logging including error level
*
* __DEBUG_LEVEL_LOG_ONLY__ Logging of debug level only
* __INFO_LEVEL_LOG_ONLY__ Logging of info level only
* __WARNING_LEVEL_LOG_ONLY__ Logging of warning level only
* __ERROR_LEVEL_LOG_ONLY__ Logging of error level only

Please create "info, warning and error" logging statement according to Debugging Logging macro. First three macros will help us to enable/disable logging and defines logging level.
Enjoy it! and say "AHO!"
