怎么改进这个程序
#include <iostream>#include <string>
using namespace std;
class user
{
double money;
string name;
public:
void add(double& mey)
{
money=money+mey;
cout<<money;
}
user(string Name,double Money);
};
user::user(string Name,double Money)
{
name=Name;
money=Money;
cout<<"please input the user's name and money:"<<name<<" "<<money<<endl;
}
void main()
{
user a("li",100);
double mey;
cout<<"input the number you want deposit"<<endl;
cin>>mey;
a.add(double& mey);//加上这句话就有错误，怎么改进实现加，且使他不出错
}
