Hi, I have a homework assignment that I am trying to accomplish and I can't seem to be able to complete.
Here are the instructions for the assignment http://www.carloscruz.info/week4_ilab.pdf
This has been discussed in this forum before, but since I can't plagerize I cant just copy it. I've however modified the program with "inspiration" from the former. Here is the link to that discussion http://www.daniweb.com/software-development/csharp/threads/342803/c-coding-question-for-newbie
Below is the code that I've managed to write so far. Any sugguestions and fixes will be greatly appreciated.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1

{
//DEFINE VARIABLES
char cD0, cD1, cD2, cD3, cD4, cD5, cD6, cD7;
string sPhone;
int iError, iCount;
do
{
//RESET COUNTER
iCount = 0;
iError = 0;
//ASK FOR INPUT
Console.WriteLine("Please enter a phone number: ");
//STORE INPUT
sPhone = Console.ReadLine();
//ASSIGN EACH CHAR INTO A VARIABLE
sPhone = sPhone.Substring(0, 8);
cD0 = sPhone[0];
cD1 = sPhone[1];
cD2 = sPhone[2];
cD3 = sPhone[3];
cD4 = sPhone[4];
cD5 = sPhone[5];
cD6 = sPhone[6];
cD7 = sPhone[7];
//SEND EACH DIGIT WITH COUNTER BY REF
ErrorCheck (iError, ref cD0, ref iCount);
iCount++;
ErrorCheck (iError, ref cD1, ref iCount);
iCount++;
ErrorCheck (iError, ref cD2, ref iCount);

Thanks!
