Banker's Dashboard

Banker’s Dashboard is a banking system consisting of a user interface and a database. The purpose of the project was to create a banking system in which a “banker” would be able to manage account records for customers. It allowed the user to create, print, find, and delete records. Upon quitting the program would write the data to a file that could later be used to read and recover the database to avoid resubmitting previous data.

For this project, I was responsible for the implementation and design of the database and the user interface. It uses a linked list data structure in which accounts are stored by increasing account numbers. I first started with the user interface and then implemented the methods that allowed the user to interact with the database. In addition to running normally, I also implemented the option to run the program with debugging statements that can assist me in developing the program by using compiling directives and makefiles. The debug statements showed which method was called and with what parameters. The debug implementation also helped with testing, which I was also solely responsible for.

Overall, this project improved my understanding of C++ and how to design a program from scratch. This experience taught me a lot about I/O in C++ and highlighted the differences of I/O between C and C++. It also taught me a lot about dynamic memory and reinforced my understanding of linked lists as a data structure. However, my favorite skill that I learned from this project was the use of makefiles and compiling directives because they made compiling more efficient and simple.

The user’s menu has 5 options for the user to choose from, allowing them to edit the database. It looks like this:

Welcome to Banker's Dashboard! 

Please type option name to select menu option.
add: Create a new customer record
printall: Print all records
find: Find a customer record
delete: Delete a customer record
quit: Quit program

I also included my implementation of adding a record to the database.

int llist::addRecord(int accNum, char name[], char address[])
{   
    record *previous;
    record *current;
    int outcome;
    record *temp;
    
    previous = NULL;
    current = start;
    outcome = 1;
  
    int debugmode = 0;
   
    #ifdef DEBUG
        debugmode = 1;
    #endif
    
    if (debugmode == 1)
    {   
        cout << "\nDebug: addRecord was called" << endl; 
        cout << "Debug: addRecord Parameters: accNum = " << accNum << ", name = " << name << ", address = " << address << "\n\n";
    }
    
    while (current != NULL && outcome == 1)
    {   
        if (accNum == current->accountno)
        {   
            outcome = -1;
        }
        else if (accNum < current->accountno)
        {   
            outcome = 0;
        }
        else
        {   
            previous = current;
            current = current->next;
        }
    }
    
    if (start == NULL || (outcome == 1))
    {   
        outcome = 0;
    }
    
    if (outcome == 0)
    {   
        temp = new record;
        temp->accountno = accNum; 
        strncpy(temp->name, name, sizeof(temp->name) - 1);
        strncpy(temp->address, address, sizeof(temp->address) - 1);
        
        if (previous == NULL) 
        {   
            temp->next = start;
            start = temp;
        }
        
        else 
        {   
            temp->next = current;
            previous->next = temp;
        }
    }
    return outcome;
}
