Question

n C# i need to

In your IDE, copy the program BorderDemo2 (in picture)

After doing so, create an overload of the DisplayWithBorder() method accepting a double type variable. Modify this method so that it works exactly like the other two versions. For example, DisplayWithBorder(3.25) would output: *3.25*

In your main method, add in the lines

DisplayWithBorder(3.25);

DisplayWithBorder(2430.49734);

this is my code

using System;
using static System.Console;

class BorderDemo2
{
static void Main()
{
DisplayWithBorder("Ed");
DisplayWithBorder (3);
DisplayWithBorder (456);
DisplayWithBorder (897654);
DisplayWithBorder("Veronica");
DisplayWithBorder(3.25);
DisplayWithBorder(2430.49734);
}

private static void DisplayWithBorder(string word)
{
const int EXTRA_STARS = 4;
const string SYMBOL = "*";
int size = word.Length + EXTRA_STARS;
int x;

for (x = 0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine();
WriteLine(SYMBOL + " " + word + " " + SYMBOL);

for (x=0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine("\n\n");
}

private static void DisplayWithBorder(int number)
{
const int EXTRA_STARS = 4;
const string SYMBOL = "*";
int size = EXTRA_STARS + 1;
int leftover = number;
int x;

while(leftover >= 10)
{
leftover = leftover / 10;
++size;
}

for (x=0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine();
WriteLine(SYMBOL + " " + number + " " + SYMBOL);

for (x=0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine("\n\n");
}

private static void DisplayWithBorder(double number)
{
const int EXTRA_STARS = 4;
const string SYMBOL = "*";
int size = (int)Math.Floor(Math.Log10(Math.Abs(number))) + EXTRA_STARS + 1;
int x;

for (x=0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine();
WriteLine(SYMBOL + " " + number + " " + SYMBOL);

for (x=0; x < size; ++x)
{
Write(SYMBOL);
}
WriteLine("\n\n");
}
}

I keep getting the error

[Running] dotnet "C:\Users\stefa\AppData\Roaming\Code\User\cs-script.user\dotnet\cscs.dll" "e:\stef C# homework\using System;.cs"

Error: Specified file could not be compiled.

e:\stef C# homework\using System;.cs(0,0): error MSB1006: Property is not valid.

the pic is the original code

using static System.Console;
class BorderDemo2
{
static void Main()
{
DisplayWithBorder("Ed");
DisplayWithBorder (3);
DisplayWithBorder (456);
DisplayWithBorder (897654);
DisplayWithBorder ("Veronica");
}
private static void DisplayWithBorder (string word)
{
const int EXTRA STARS = 4;
const string SYMBOL = '';
int size = word. Length + EXTRA_STARS;
int x;
for (x=0; x< size; ++x)
Write (SYMBOL);
WriteLine();
WriteLine(SYMBOL + " " + word +
for (x=0; x< size; ++x)
Write (SYMBOL);
WriteLine("\n\n");
}
private static void DisplayWithBorder(int number)
{
const int EXTRA STARS = 4;
const string SYMBOL = "";
int size EXTRA STARS + 1;
int leftover number;
int x;
while(leftover >= 10)
{
leftover leftover / 10;
++size;
}
for (x=0; x< size; ++x)
Write (SYMBOL);
WriteLine();
WriteLine(SYMBOL + ""+number +
for (x=0; x< size; ++x)
+ SYMBOL);
Write(SYMBOL);
WriteLine("\n\n");
+ SYMBOL);
