(C# HELP) Keeps Saying Namespace is not found

Question

It's saying that the namespace for, "visitor" and "person" is not found. I'm stuck. Do I have to declare both as strings?

------------------------------------------------------------------------------------------------

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
namespace Rextester
{
public class Program
{
public static void Main(string[] args)
{
Person p1 = new vistor();
System.Console.WriteLine("What's your first name?");
p1.fName = System.Console.ReadLine();
System.Console.WriteLine("Now tell me your last name.");
p1.lName = System.Console.ReadLine();
System.Console.WriteLine("Please tell me your age now.");
p1.Age = int.Parse(System.Console.ReadLine());
p1.Lover = new vistor();
Person.TotalofAllAges + Person.TotalofAllAges + p1.Age;
p1.PrintNameAndAge();
System.Console.WriteLine("What's your lover's name?");
p1.Lover.fName = System.Console.ReadLine();
p1.Lover.lName = p1.lName;
System.Console.WriteLine("What's their age?");
p1.Lover.age = int.Parse(System.Console.Readline());
p1.Lover.Lover = p1;
Person.TotalofAllAges = Person.TotalofAllAges + p1.Lover.Age;
p1.Lover.PrintNameAndAge;
Console.WriteLine("Press P to go on");
Console.ReadLine();
}
}
}

Answer 1

Hello, you are instantiating Person and Visitor as class object, but it will not work if you don’t create the Persone and Visitor class object first.
for example:
public class Person
{
public string fName;
public string lName;
}

after you create the person class you can use it:

public static void Main(string[] args)
{
Person p = new Person();
p.fName = Console.ReadLine();
p.lName = Console.ReadLine();
Console.WriteLine(p.fName + “ “ + p.lName);
}

Besides if you declare using System; at the top you dont need to write it everytime like you did:
System.Console.ReadLine() -> just write Console.ReadLine()
