C# Help Credit.cs

[eriekasato]

Write a method named CustomerCreditLimit() that
accepts a double as a parameter and displays the value
as the amount of credit granted to a customer. Provide a
default value for the method so that if a program calls the
method without using an argument, the credit limit displays
$500. Write a console-based program with a Main()
method that proves the credit limit method works correctly
whether it is called with an argument or not. Save
the file as Credit.cs.

What are you lost with? Sorry but we need you to be a bit more specific.

[ddanbe]

You should be more specific in your questioning, as Ketsuekiame already pointed out.
I'm inferring it could have something to do with method overloading

I think perhaps you've misunderstood the assignment. Here's some revised code that should make it clearer:

    static void Main(string[] args)
    {
        double balance = 0.00;
        Console.WriteLine("Current credit limit is : " + CustomerCreditLimit().ToString());
        Console.Write("Enter the customer current balance: ");
        balance = Convert.ToDouble(Console.ReadLine()); 
        Console.WriteLine("The credit limit for this balancxe is : " + CustomerCreditLimit(balance).ToString());
        Console.ReadLine();
    }
    public static double CustomerCreditLimit(double balance = 500)
    {
        double newcreditlimit = 500;
        if(balance > 500)
            newcreditlimit = balance;
        return newcreditlimit;
    }
