(E.g. : +-*/, <<, >> =, <>) Operator Precedence and Associativity (E.g. : !, -, div, mod) Compile Time Functions Type conversion Numeric functions Character-Classification functions (E.g. : isAlpha, isDigit, isSpace) String functions Symbol information (E.g. : @size, @define @typeName, @elements, @elementSize) Misc compile time functions (E.g. : @odd,…
