c++继承与派生试验报告

第七章继承与派生实验目的学习声明和使用类的继承关系，声明派生类熟悉不同继承方式下对基类的访问控制学习使用虚基类解决二义性问题实验内容7.1#include<iostream>usingnamespacestd;classanimal(public:private:intage;);classdog:publicanimal(public:voidsetage(intn);private:);voiddog::setage(intn)(age=n;)intmain()(dogd1;d1.setage(5);return0;无法访问age,因为公有继承的继承规则是基类的私有类不可访问、#include<iostream>usingnamespacestd;classanimal(public:intage;private:)；classdog:publicanimal(public:voidsetage(intn);private:);voiddog::setage(intn)(age=n;)intmain()(dogd1;d1.setage(5);return0;)把age移至1」private里即可7.2#include<iostream>usingnamespacestd;classbaseclass(public:baseclass(intn)(number=n;cout<<"调用了基类的构造函数"<<endl;)~baseclass()(cout<<"调用了基类的析构函数"<<endl;)private:intnumber;);classderivedclass:publicbaseclass(public:derivedclass(intn):baseclass(n)(cout<<"调用了派生类的构造函数"<<endl;)~derivedclass()(cout<<"调用了派生类的析构函数"<<endl;)private:)；intmain()(derivedclassd(3);return0;)白UW*g他用LZ向!■，鹏■上■iKoistf%睢油一Q 中3■,Snrcrij仃口nan^pfi训…调用了港生堂的的诙酸白UW*g他用LZ向!■，鹏■上■iKoistf%睢油一Q 中3■,Snrcrij仃口nan^pfi训…调用了港生堂的的诙酸7/11'4 D»五:Kxfci 、--..2amtinu^3 'GecOfrjMogvUiCM~CpfXhKi..EpffhKt Dkdik.
