其中包括前后加/减（i++、--foo）， 加减乘除赋值运算符（a+=3、b*=2、c/=2.2、d-=6.2）。

These include pre- and post-increment/decrement ( i++, --foo ), add/sub/mult/div assign operators ( a+=3, b*=2, c/=2.2, d-=6.2 ).

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。

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