Help with understanding class

rovert456 (32)
I thought I had figured out how to create classes, until I had to use numbers in them. The example I was given did not use them, and the problem for my assignment has almost nothing to do with the example. My problem is that I'm not sure how to go forward with implementing the use of a static random number generator, or the addition of an array.

Here's the assignment:
Define the class bankAccount to implement the basic properties of a
bank account. An object of this class should store the following data:
Account holder’s name (string), account number (int), account
type (string, checking/saving), balance (double), and interest rate
(double). (Store interest rate as a decimal number.) Add appropriate
member functions to manipulate an object. Use a static member
in the class to automatically assign account numbers. Also declare
an array of 10 components of type bankAccount to process up to
10 customers and write a program to illustrate how to use your class.

line 8 is filling in the parameters of line 26 from the previous post.
bankAccount(string name = "", string type = "", int num = 0, double bal = 0.0, double rate = 0.0);

so you need
bankAccount owner("some_name", "type like savings or something") ; //the rest default to zero OR
bankAccount owner("some_name", "type like savings or something", 3, 152.75, 0.02) ; //override the zeros

because you also did defaults on the strings, you can treat this like a default ctor though it is NOT technically one. /shrug.

Thank you jonnin, I wasn't sure if that's what I was meant to to or not for that spot, or if my code was working so far to even do that
