/**
* @file
* @brief Demonstration of mixed c++ and c user application with pure c RIOT
* - mixing of c and c++ source to test name mangling
* - introducing a namespace to declarative block, avoiding to qualify calls, e.g. std::vector
* - using private and public member functions, e.g. 'cpp_obj.greet()' cannot be accessed from main.cpp
* - overloading of function 'cpp_obj.say_hello(...)' for 'none', 'int' or 'float'
* - demonstration of templated c++ container 'std::vector'
* - usage of iterator to access elements of the container type
