// Inline functions’ definitions must be found in the compilation unit in which they are used.

// Try putting this definition in DayOfYear.cpp, remove it from here, and recompile. You will
// get an error.
// In other words, inline functions have internal linkage. If you want to make an inline function
// accessible to other compilation units, they must include the definition of the inline function.
