// climits <limits.h>
// https://devdocs.io/cpp/header/climits
// This header was originally in the C standard library as <limits.h>.
//
// This header is part of the type support library, in particular it's part of the C numeric limits interface.
// <float.h>
// https://www.tutorialspoint.com/c_standard_library/float_h.htm
//
// The float.h header file of the C Standard Library contains a set of various platform-dependent constants related to floating point values. These constants are proposed by ANSI C. They allow making more portable programs.

The moonlight’s beams, so pure and bright, Translucent, yet a sorrowful sight, As they pass through the window at night, A melancholic feeling takes flight. The light, so pale, and yet so strong, It casts a shadow, oh so long, And in the silence, it sings a song, Of love and loss, of right and wrong.
