Naming Conventions: amountPaid vs. paidAmount [closed]

Question

here is two samples with two different approaches to naming variables:

decimal amountDue = 1000;
decimal amountPaid = 800;

vs.

decimal dueAmount = 1000;
decimal paidAmount = 800;

Which one would you usually prefer and why?

Answer 1

You should use which ever one reads better as an english sentence. Such as the amount due to the customer is 1000 dollars. In my opinion #1 is better. Because if you write the customer is due the amount of 1000 dollars, it breaks up the wording of the actual variable.

Answer 2

Whatever is most readable in the given context. I could see this ranging from either of your options to simply "paid" and "due".

For example:

public decimal RemainingAmount( Invoice invoice, int quantity, Coupon[] coupons )
{
     decimal paid = coupons.Sum( c => c.Value );
     decimal due = invoice.Price * quantity;

     return due - paid;
}

Answer 3

The first one (amountDue) means typing seven characters before getting useful intellisense. I'd opt for number two.
