Bank Database Application in C

This program serves as a bank record management system. I programmed both the database and the user interface of the application. The user-interface displays a menu of options that a banker can choose from to manage the bank's records. The UI takes in input and displays records. The UI calls functions from the database. Some of the essential functions I wrote for the database include the addRecord, deleteRecord, findRecord, and printAllRecord functions. The database also has functions that read from and write to record files, allowing records to be saved after exiting the program.

This project heavily emphasizes the use of pointers and structures, which are the foundations of the database. This project demonstrates the use of Makefiles to execute the program. Overall, I've developed my understanding of C or procedural languages and enhanced my debugging and project design skills.

Below is an example of one of my database functions, findRecord, which finds and displays a bank record given the account number.

int findRecord (struct record * start, int uaccountno)
{   
    struct record * temp = start;
    int success = 1;
    
    if (start == NULL)
    {   
        success = -1;
    }
    
    while (success == 1 && temp != NULL)
    {   
        if (uaccountno == temp->accountno)
        {   
            printf("Account Number: %d\n", temp->accountno);
            printf("Name: %s\n", temp->name);
            printf("Address: %s\n", temp->address);
            success = 0;
        }
        else if (temp->next != NULL)
        {   
            temp = temp->next;
        }
        else
        {   
            success = -1;
        }
    }
    if (debugmode == 1)
    {   
        printf("\n-debugmode-\nFunction called: findRecord()\n");
        printf("int uaccountno: %d\n", uaccountno);
        printf("Return value: %d\n\n", success);
    }
    return success;
}
