c语言重载(overriding in C)或函数不定参数个数 google一下 c overiding发现有这样一段英文解释: Because C doesn't require that you pass all parameters to the function if you leave the parameter list blank in the prototype. The compiler should only throw up warnings if the prototype has a non-...

Method overloading and overriding are two common forms of polymorphism ( the ability for a method or class to have multiple forms) in C# that are often confused because of their similar sounding names. In this article, we show the difference between the
However, if we create an object of the base class as shown in function(c) "b.msg()" and call it, it will use the original version from the base class. In short, function overriding occurs when the functionality of the base class is redefined in the derived class. When an object of...
that will override a base classvirtualmethod of a different name but the same signature. You'll also notice that thenewslotkeyword has been added to the method definition so that a newvirtualmethod will be generated. In this way, even if the base class had a method of the same name, th...
“name hiding” 是指在类的继承层次中,基类和子类共享想同名字的变量或者方法,从而导致父类的名称在子类中不可见。 这种现象在c中也很普遍,比如: intiCnt =1; func(inti) {intiCnt =2};//在这个函数中,所有和iCnt相关的操作都是使用函数的局部变量,这时外部的iCnt被隐藏。
