各位大侠，请帮我看看我的代码错在哪儿？

#include<iostream>
using namespace std;
#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 SetNumber(const string&snumber){number=snumber;}
        void SetAuthor(const string&sauthor){author=sauthor;}
        void SetPrice(float sprice){price=sprice;}
        void SetTotal(const string&T,const string&N,const string&A,float P )
        {
                title=T;
                number=N;
                author=A;
                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","34.1");
        cout<<"书名："<<love.Gettitle()<<"作者："<<love.GetAuthor()<<"编号："<<love.GetNumber()<<"价格："<<love.GetPrice()<<endl;

return 0;
}


以下是报错信息：

执行 cl.exe 时出错.

编译错误不是说了么，cannot convert parameter 4 from 'char [5]' to 'float'
改成
book love("love","Jacky","001",34.1);

已经发现两个错误地方：
1：book love("love","Jacky","001","34.1");----> book love("love","Jacky","001",34.1f);
2：C:\test\dmcy\dmcy.cpp(43) : error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'const class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptable conversion
)--------------------------------------------------------->编写一个string.h头文件.即可
