Thread: Help with Linked Lists - C++

I'm trying to build a banking program with the capability to create new accounts (savings or checking), process a deposit, process a withdrawal, or print one or all of the accounts at this "bank". I am doing this utilizing two classes, one for 'Checking' and one for 'Savings'.


I've more or less written all of the code needed but I could use some help utilizing linked lists in a few spots that are commented within my 'main' function where I am needing to search through my classes and then send the proper 'Savings' or 'Checking' variable to my class functions. I've had issues implementing linked lists for classes and my textbook along with online sources have not helped me understand proper usage of them.


If it help, comments of this variety occur in lines: 191, 192, 198, 203, 228, 230, 241, 243, 269, 271, 282, 284, 312, 314, 325, 327, 335, 337, 342, 344


Thanks in advance for any assistance.
