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?

Verizon will block up to 5 numbers for 90 days, but after that you will have to pay a small monthly fee. Currently, these providers do not offer the ability to block a specific number from calling. T-Mobile currently does not offer a native way to block numbers from calling or texting your mobile phone.
