7.41 谨慎使用方法重载(overloading) 以下类对不同的集合类型分类,classify()方法被重载: 以下测试将失败: 重载方法的选择是在编译时决定的(即为静态选择,而覆盖方法的选择是在运行时选择的,即动态选择),如果被重载的方法具有相同的参数个数,并且参数类型之间具有继承关系(如上例参数类型Set继承Collection),那么...

Function Overloading In C++, there are many complex levels of function overloading, with some defined as "better" matches than others. If the code designer takes advantage of the more subtle behaviors of overload function selection, the code can become difficult to maintain. Not only will it...
