Review the solution to display email addresses

Completed

The following code is one possible solution for the challenge from the previous unit.

	string[,] corporate = 
	{
		{"Robert", "Bavin"}, {"Simon", "Bright"},
		{"Kim", "Sinclair"}, {"Aashrita", "Kamath"},
		{"Sarah", "Delucchi"}, {"Sinan", "Ali"}};

	string[,] external = 
	{
		{"Vinnie", "Ashton"}, {"Cody", "Dysart"},
		{"Shay", "Lawrence"}, {"Daren", "Valdes"}
	};

	string externalDomain = "hayworth.com";

	for (int i = 0; i < corporate.GetLength(0); i++) 
	{
		DisplayEmail(first: corporate[i,0], last: corporate[i,1]);
	}

	for (int i = 0; i < external.GetLength(0); i++) 
	{
		DisplayEmail(first: external[i,0], last: external[i,1], domain: externalDomain);
	}

	void DisplayEmail(string first, string last, string domain = "contoso.com") 
	{
		string email = first.Substring(0, 2) + last;
		email = email.ToLower();
		Console.WriteLine($"{email}@{domain}");
	}

This code is just "one possible solution" because you might have added line feeds in different spots, used variables differently, or formatted the code differently.

Regardless of minor code differences, your method should apply the default value of an optional parameter to display contoso.com.

When you run the code, you should see the following output:

	robavin@contoso.com
	sibright@contoso.com
	kisinclair@contoso.com
	aakamath@contoso.com
	sadelucchi@contoso.com
	siali@contoso.com
	viashton@hayworth.com
	codysart@hayworth.com
	shlawrence@hayworth.com
	davaldes@hayworth.com
