第11讲面向对象编程基础（2）本讲内容一、值类型与引用类型值类型与引用类型值类型与引用类型多个实例共享一个型，但各自存储自己的属性二、继承与多态概况请开“马自达车”！从“有病”说起#include<stdio.h>voidPrintHelp();voidDriveVolvo();voidDriveBenz();voidDriveMazda();main(intargc,char*argvs[]){if(argc<2){PrintHelp();return;}if(strcmp(argvs[1],"V")==0)DriveVolvo();elseif(strcmp(argvs[1],"B")==0)DriveBenz();elseif(strcmp(argvs[1],"M")==0)DriveMazda();elsePrintHelp();解决办法什么是“继承”机动车Musician单继承与多继承“继承”关系的代码实现继承（续）usingSystem;publicclassBase{publicinta=10;}publicclassDerived:Base{}publicclassClient{publicstaticvoidMain(){Derivedd=newDerived();Console.WriteLine(d.a);}}usingSystem;publicclassBase{publicstaticinta=10;}publicclassDerived:Base{}publicclassClient{publicstaticvoidMain(){Derived.a=15;Console.WriteLine(Base.a);}}usingSystem;publicclassBase{publicvoidSayHello(){Console.WriteLine("Hello!");}}publicclassDerived:Base{}publicclassClient{publicstaticvoidMain(){Derivedd=newDerived();d.SayHello();}}usingSystem;publicclassBase{publicstaticvoidSayHello(){Console.WriteLine("Hello!");}}publicclassDerived:Base{}publicclassClient{publicstaticvoidMain(){Derived.SayHello();}}usingSystem;publicclassBase{privateinta=10;publicvoidShowA(){Console.WriteLine(a);}}publicclassDerived:Base{}publicclassClient{publicstaticvoidMain(){Derivedd=newDerived();d.ShowA();}}继承（续）多态（PolyMorphism）“多态”案例“多态”案例（续）多态特点面向对象三要素面向对象学习顺序小结小结（续）
