It's dangerous to code alone! Take this.

The Defense of Consolas

The following is one possible solution to this challenge.

Console.Title = "Defense of Consolas";

Console.Write("Target Row? ");
int row = Convert.ToInt32(Console.ReadLine());

Console.Write("Target Column? ");
int column = Convert.ToInt32(Console.ReadLine());

Console.ForegroundColor = ConsoleColor.Red;

Console.WriteLine($"({row}, {column - 1})");
Console.WriteLine($"({row - 1}, {column})");
Console.WriteLine($"({row}, {column + 1})");
Console.WriteLine($"({row + 1}, {column})");

Console.Beep();
