Constructor It can have any type of parameters,but can't have returning type.So when defining and declaring a constructor,you can't point out its type,even the “void'type. It may be inline functions,overloading functions, functions without format parameters. In practice,you usually need define a constructor for each class.If you haven't define a constructor,the complier will automatically create a constructor without a parameters. 2017年4月26日12时 H05务 第9章关于类和对象的进一步讨 论 BACK NEXTHOME2017年4月26日12时 15分 第9章 关于类和对象的进一步讨 论 5 uIt can have any type of parameters, but can’t have returning type.
