Virtual functions ensure that the correct function is called for an object, regardless of the expression used to make the function call. Suppose a base class contains a function declared as virtual and a derived class defines the same function. The function from the derived class is invoked for objects of the derived class, even if it is called using a pointer or reference to the base class.
Now we may need to add a line, and I was wondering how much it would cost for the additional phone? I know that when adding a line its an additional $10 to the plan, but are there any discounts on the phones for the new line, or will it need to be paid for at its full retail price?ow we may need to add a line, and I was wondering how much it would cost for the additional phone?

Report Abuse. I just added my sister in law to our verizon wireless account. To add a line-it costs $9.99 per month. However, my sister in law (and I'm sure your son) probably wants text messaging.Text messaging adds anywhere from 10 to 20 dollars a month onto your cell phone bill.It is also important to make sure he doesn't go over on his minutes because that will raise your bill again.est Answer: It depends what single plan you are on. If you are on a basic $39.99 450 plan, you would have to move into a 59.99 700 min family share plan. This covers his phone, plus yours. Some phones are free! Sometimes stores make exceptions for new lines as well.
