下面的程序是为了说明truct也能和class一样，但是不知道为什么会有这么多错误，请高手帮忙看看
#include<iostream>
using namespace std;
enum breed{ golden, cairn,dandie,shetland,doberman, lab};
struct mannal
{
public:
    mammal():itsage(2),itsweigh(5){}
    ~mammal(){}

    int getage()const
    {
        return itsage;
    }
    void setage(int age)
    {
        itsage=age;
    }
    int getweight() const
    {
        return itweight;
    }
    void setweight(int weight)
    {
        itsweight=weight;
    }
    void speak()const
    {
        cout<<"mammal sound"<<endl;
    }
    void sleep()const
    {
        cout<<"I'm sleeping"<<endl;
    }
protected:
     int itsage;
    int itsweight;
};
struct dog:public mammal
{
public:
    dog():itsbreed(golden){}
    ~dog(){};
    breed getbreed()const
    {
        return itsbreed;
    }
    void setbreed(breed breed)
    {
        itsbreed=breed;
    }
    void wagtail()const
    {
        cout<"tail wagging"<<endl;
    }
    void begforfood()const
    {
        cout<<"begging for food"<<endl;
    }

private:
    breed itsbreed;
};
void main()
{
    dog fido;
    fido.speak();
    fido.wagtail();
    cout<<"fido is "<<fido.getage()<<"years old"<<endl;

}

mannal
类名写错了

谢谢楼上的，不过还是错很多

LZ真是粗心啊...
基本都是拼写错误...
你应该自己能发现才是啊...
看下面吧,共四处我全标出来了...
