求给位帮忙看看这图书类 哪儿错了...
#include "String.h"
class book
{
public:
book();
book(char*,char*,char*,float);
const String& GetTitle()const{return title;}
const String& GetAuthor()const{return author;}
const String& GetNumber()const{return number;}
float GetPrice()const{return price;}
void SetTitle(const string&Stitle)
{title=Stitle;}
void SetAuthor(const string&SAuthor)
{author=Sauthor;}
void SetNumber(const string&Snumber)
{number=Snumber;}
void SetPrice(const string&Sprice)
{price=Sprice;}
void setTotal(const string&T,const String&N,const String&A,float P)
{
title=T;
author=A;
number=N;
price=P;
}
private:
String title;
String author;
String number;
float price;
};
book::book():title(""),author(""),number(""),price(0)
{
}
book::book(char*Title,char*Author,char*Number,float Price):title(Title),author(Author),number(Number),price(Price)
int main()
{
book love("love","Jacky","001",34.1f);
cout<<"book name: "<<love.GetTitle()<<"book author: "<<love.GetAuthor()<<"book nunmber: "<<love.GetNumber()<<"book price: "<<love.Price()<<endl;
return 0;
}

[解决办法]
什么错误？String.h是什么文件嘛？自己定义的么？你用的是什么编译器？
