In this short article, I have posted an example that does the reinterpret_cast on an integer and convert it to char pointer and then the value pointed by the char pointer is converted to r-value reference all in a macro.
Enumerations are always fun to use in C++ programs. C++ core guidelines define eight different rules to define the enumerations. And also, C++11 introduced the scoped enumerations also called as class enumerations. Scoped enums also have few advantages over plain enums which are also covered in this article.
Overloaded functions have the exact same code but the type is different. It seems an unnecessary overhead to write the same code again and again and in a long time it adds up to the maintenance cost of the project. To write code once and use it multiple times we use function templates. A function template is itself is not a definition of a function; it is a blueprint for defining a family of functions.
