✅ RPN calculator
I am coding a RPN calculator and I am supposed to do the calculator.view part and I just want to make sure I am doing it right. This is the code I have written so far and I attached the instructions.
//Calculator.view//
using System;
using System.IO;
namespace Calculator.View
{
public class Calculator
{
public string GetRPNString()
{
Console.WriteLine();
return Console.ReadLine();
}
}
}
namespace Calculator.View
{
public class UserInput
{
public void DisplayResult(double ResultString)
{
Console.WriteLine("Result:" + ResultString);
}
public void DisplayError(string ErrorMessage)
{
Console.WriteLine("Error: " + ErrorMessage);
}
}
}
namespace Calculator.View
{
public class FileInput
{
private string FilePath;
public FileInput(string filePath)
{
FilePath = filePath;
}
public string ReadInputFromFile()
{
using (StreamReader reader = new StreamReader(FilePath))
{
return reader.ReadLine();
}
} } } namespace Calculator.View { public class FileOutput { private string FilePath; public FileOutput(string filePath) { FilePath = filePath; } public void WriteOutputToFile(double result) { try { using (StreamWriter writer = new StreamWriter(FilePath)) { writer.WriteLine(“Result: “ + result); } } catch (Exception ex) { Console.WriteLine(“Error writing to file: “ + ex.Message); } } } }
} } } namespace Calculator.View { public class FileOutput { private string FilePath; public FileOutput(string filePath) { FilePath = filePath; } public void WriteOutputToFile(double result) { try { using (StreamWriter writer = new StreamWriter(FilePath)) { writer.WriteLine(“Result: “ + result); } } catch (Exception ex) { Console.WriteLine(“Error writing to file: “ + ex.Message); } } } }

I changed the code so that I only have one class view instead but I am still not sure if this is correct
Didn't you post the same thing yesterday?
Yes but I have changed it now and I did not get help
Does this look correct I have the namespace calculator.view, the class view, the attributes ErrorMessage, ResultString, InputString, the methods GetRPNString, DisplayResult and DisplayError. And I am using StreamWriter to write to the file

Sorry, but I'm not really interested in marking your code against an assignment. That's your teacher's job. I'm happy to answer specific questions, but "mark my homework" isn't really interesting to me. Good luck!
