求大神帮忙看看下面这段代码错在哪里了呗

关于类的继承与派生的，自己写的，有错误，但是自己改不了，大神帮忙看看呗，谢谢了

#include <iostream>
#include<cstring>
using namespace std;
/* run this program using the console pauser or add your own getch, system("pause") or input loop */
class glasses{
public:
glasses(){
}
glasses(char n[],int p,float l){
strcpy(name,n);
price=p;
lifetime=l;
}
void set(char n[],int p,float l){
strcpy(name,n);
price=p;
lifetime=l;
}
void show(){
cout<<name<<price<<lifetime<<endl;
}
~glasses(){
}
protected:
char name[20];
int price;
float lifetime;
};
