Introduction

This portfolio will showcase what was learned over the last weeks. The program within a console command, will convert 3 binary numbers into decimals. With every binary input it checks whether the given value is correct, and in case of an incorrect input it warns you, and asks for a new input. After the conversion it shows the input binaries and the result in the decimal values. After writing out the result you have a chance to continue by inputting ’’Y’’, ’’y’’, ’’Yes’’ or ’’yes’’

Source Code

using System.Collections.Generic; using System.Linq; using System.Text;

namespace Portfolio2

{

class Program

{

static void Main(string[] args)

{

// declare variables int iNum1; int iNum2; int iNum3; int iDec; string sChoice;

sChoice = "Y"; // determine variable to first loop

//continuing control

while (sChoice == "Y" || sChoice == "y" || sChoice == "Yes" || sChoice ==

"yes")

{

// header

Console.WriteLine("Binary to decimal Converter"); Console.WriteLine("---------------------------");

// obtain first number

Console.WriteLine();

Console.Write("Enter digit 1: ");

iNum1 = Convert.ToInt32(Console.ReadLine());

// validate user input while (iNum1 > 1 || iNum1 < 0)

{

Console.Write("You must enter 0 or 1 , please re-enter: "); iNum1 = Convert.ToInt32(Console.ReadLine());

}

// obtain second number

Console.WriteLine();

Console.Write("Enter digit 2: ");

iNum2 = Convert.ToInt32(Console.ReadLine());

// validate user input while (iNum2 > 1 || iNum2 < 0)

{

Console.Write("You must enter 0 or 1 , please re-enter: "); iNum2 = Convert.ToInt32(Console.ReadLine());

}

// obtain third number

Console.WriteLine();

Console.Write("Enter digit 3: ");

iNum3 = Convert.ToInt32(Console.ReadLine());

// validate user input while (iNum3 > 1 || iNum3 < 0)

{

Console.Write("You must enter 0 or 1 , please re-enter: "); iNum3 = Convert.ToInt32(Console.ReadLine());

}

// calculate the result and show it iDec = iNum3 + iNum2 * 2 + iNum1 * 4;

Console.WriteLine();

Console.WriteLine(iNum1 + "" + iNum2 + "" + iNum3 + " converted to decimal is " + iDec);

// input to continue

Console.WriteLine();

Console.Write("Do you wish to continue? ");

sChoice = Console.ReadLine();

Console.Clear();

}

}

}

}

Description of testing

During the testing phase I have tried all possibilities of the three binary and their results.

The result table

Digit 1	Digit 2	Digit 3	Decimal
0	0	0	0
0	0	1	1
0	1	0	2
0	1	1	3
1	0	0	4
1	0	1	5
1	1	0	6
1	1	1	7

I didn't use any references to do my portfolio 2 only what I learned on the lectures and tutorials.

Big thanks to my teachers!
