So, when I run the program and try to list all the information I get an interesting error message that pops up:
-----
Debug Assertion Failed!
Program: ...ocuments\Programs\C + +
Programs\Checkbook\Debug\Checkbook.exe
File: f:\dd\vctools\crt_bld\self_x86\crt\src\tccpy_s.inl
Line: 19
Expression: (((_Src))) != NULL

Though I have an idea that it probably has something to do with the if statement
regarding the list function, but I don't really get what's wrong with it. Also, I need a little help with the balance function. its suppose to keep track of how much money is left in the balance. So depositing would add money to the current balance and writing a check would decrease from the current balance. I was hinted of using strings to integers but I have no idea where to start, Thanks for any help. Below is my code:
*Also there's suppose to be a text file which the program reads and writes to, name it Checkbook.txt
