Can someone take a look at this code/Destructor Help

[Cirabou]

Hello, everyone.
Below is the code for an ATM machine. I am trying to program in a destructor method that will allow the user to close the program.
Every time I run the damn thing, I get this error:



" type `double' argument given to `delete', expected pointer "

I'm not sure how to fix it. Could someone please help? I'm very sleepy and I tried reading up on pointers but couldn't understand it.

call delete only on objects where you previously called new. Since you don't have any dynamic memory there's no need for a delete.

Seems that you misunderstand the use of a destructor? What do you think a destructor does?
