Question

Write the program WritePatientRecords that allows a doctor’s staff to enter data about patients and saves the data to a file called Patients.txt. The output should be in the following format: p#, PATIENT_NAME, BALANCE. Create a Patient class that contains fields for ID number, name, and current balance owed to the doctor’s office.

using System;
using static System.Console;
using System.IO;
class WritePatientRecords
{
static void Main()
{
// Your code here
}
}

Answer 1

/*C # program that prompts user to enter id ,name and balance owed to doctor .Then prompt continues until user enters 0 to stop reading. Then write the data to the file,Patients.txt . */
//WritePatientRecords.cs

    class WritePatientRecords

        {
            //string set to file name
            string filename="Patients.txt";
            //create an object,writer

            decimal balance;
            Console.Write ("Enter Patient #id or 0 to exit: ");
            //read id and parse to integer value
            int.TryParse (Console .ReadLine () , out id);
            /*Read data from user until id is not 0*/
            while (id!=0)
