There are many examples covering the range from simple (addition/subtraction overloading) to the complex (overloading numeric constants and run-time overloading).

本书中有大量的例子，从简单（加减操作符的重载）到复杂（重载数值常量以及运行时间等）一应俱全。

Function overloading permits one function-name to define multiple functions. Function overloading enables program-design simple.

函数重载允许一个函数名定义多个函数，函数重载使程序设计简单化。
