So basically I'm making a bank application for a linked list and I'm having an issue as to how I'm supposed to create the withdraw and deposit function as you can see in my code I wish to be able to utilize this as part of my linked list.
The deposit function is in line 888 and im using else if option 4 in line 204 to call this function to work
If possible could somebody help me in my code as to get this function working please as i've had success with the other functions so far as of up till now
What I have tried:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include <list>
