The document discusses inline functions in C++. It explains that inline functions are replaced by their function code during compilation so they run faster than regular functions but use more memory. It provides examples of declaring and defining inline functions and demonstrates how an inline function call is handled at runtime by replacing it with the function statements. The document also discusses making member functions inline within a class declaration.
