    textfile questions

    i have a couple questions about textfiles...

    1. how do you make a folder to put the textfile into?

    i want to have a folder that uses the first and last name given from user input that would hold the textfile specific to that person

    2. how do you make it so u can log into that folder using a password and recall info from the textfile.

    the information that goes into the textfile is input which is the first name and last name, which they must use to log in, as well as a 7 digit password. so now there in there account and that tells them what there statement balance is from last time and they can put more in or take some out in the deposits and withdrawls.



    Code:
    //This program written by Dan Kemper
    //This program will balance your checkbook and print the results to a textfile named "checkbook.txt" or print the scrren to your printer
    //Suggestions and other comments can be sent to my email: crashingintoclouds@gmail.com

    using namespace std;	
    
    int main ()
    {
       //Declares variables
       char FirstName[20];
       char LastName[30];
       char Account[9];
       int PrintStatement;
       float Balance;
       float Deposits;
       float Withdrawls;
       float NewBalance;
    
    
       //Makes Textfile
       ofstream outfile ("checkbook.txt",ios::trunc);
       
       //Outputs to screen
       cout << "       AAA         TTTTTTTTTTTTTTT  MMMMM             MMMMM\n";
       cout << "      AAAAA        TTTTTTTTTTTTTTT  MMMMMM           MMMMMM\n";
       cout << "     AAA AAA            TTTTTT      MMM MMM         MMM MMM\n";
       cout << "    AAA   AAA           TTTTTT      MMM  MMM       MMM  MMM\n";
       cout << "   AAAAAAAAAAA          TTTTTT      MMM   MMM     MMM   MMM\n";
       cout << "  AAAAAAAAAAAAA         TTTTTT      MMM    MMM   MMM    MMM\n";
       cout << " AAA         AAA        TTTTTT      MMM     MMM MMM     MMM\n";
       cout << "AAA           AAA       TTTTTT      MMM      MMMMM      MMM\n";
       
       cout<<"\nPress [ENTER] to continue...\n";
       cin.get();
       
       cout << "\n\nThis program balances your checkbook.\n\n";
       cout << "First Name: ";
    
       //Asks user for input
       cin.get(FirstName, 20);
       cin.ignore(80, '\n');
       cout << "Last Name: ";
       cin.get(LastName, 30);
       cin.ignore(80, '\n');
       cout << "Account number: ";
       cin.get(Account, 9);
       cin.ignore(80, '\n');
       cout << "\n\nStatement balance: ";
       cin >> Balance;
       cin.ignore(1);	
       cout << "\nOutstanding deposits: ";
       cin >> Deposits;
       cin.ignore(1);

       //Conversions
       NewBalance = Balance + Deposits - Withdrawls;
    
       //Output Results
       cout << "\nNew balance: ";
       cout << setiosflags (ios::fixed) << setprecision(2) << NewBalance;
       
       cout << "\n\nDo you want the above information to be printed to a textfile? (Y/N)\n";
       cin >> PrintStatement;
       cin.ignore(1);	
    do
    {
       //Prints to Textfile
       outfile << "Name: " << FirstName << " " << LastName << "\n";
       outfile << "Account Number: " << Account << "\n";
       outfile << "Statement Balance: " << Balance << "\n";
       outfile << "Outstanding Deposits: " << Deposits << "\n";
       outfile << "Outstanding Withdrawls: " << Withdrawls << "\n";
       outfile << "New Balance: " << setiosflags (ios::fixed) << setprecision(2) << NewBalance;            
    }
    while (PrintStatement=='y' || PrintStatement=='Y');
    
    cout << "Thank You!";
       
       outfile.close();
       
       //Stops program until button is pressed
       cin.get();
       return 0;
    }

    i guess that was pretty hard to understand what i'm goin for huh?

    okay i want it to open the ATM thing to show up with the "press ENTER..." changed to "Type [r] if your a registered user, type [u] if your unregistered and wish to make an account, or press [q] to quit." ...waits for user input...

    if "r" then you type your full name (first and last name) and 7 digit account number which if correct will recall your previous balance (from a textfile made after registering located in a folder with the users full name as the title)and will ask for more input (deposits and withdrawls) which will alter the balance and save it back into the textfile for later use.

    if "u" then it asks for your first and last name as well as deposits which will decide your balance and your 7 digit password and saves it to a textfile (textfile names after date and time) when asked if all above information is true and makes a folder titled with the name of users full name which holds the textfile.

    can anyone help me? i think i'm just tryin to do too advanced stuff for my noobish abilities as of this point.

    I'd recommend you start using C++ strings with <string>.

    If you were to use them, maybe something like this would be a start:
    Code:
    char status;
    cout << "Are you already registered?  Please enter \"r\" if yes, \"u\" if unregistered: ";
    cin >> status;
    
    string first, last;
    cout << "Please enter your first and last name: ";
    cin >> first >> last;
    
    if (status == 'u' || status == 'U')
    {
    	// makes a system call to create a directory with the first & last name
    	string syscall = "mkdir " + first + last;
    	system( syscall.c_str() );
    }
    
    // makes the filepath "\firstlast\checkbook.txt" - will already exist if registered, or was just
    // created if they were unregistered
    string filepath = "\\" + first + last + "\\checkbook.txt";
    ofstream outfile( filepath.c_str() );
    
    // Do all that deposit/withdrawl stuff
    Naturally not guaranteed to work since I just wrote it without testing and there may be an obvious flaw and I'm not that awesome at coding...Hope it helps though.

    Creating dir is OS specific. For Linux:

    #include <sys/stat.h>
    #include <sys/types.h>

    int mkdir(const char *pathname, mode_t mode);

    For Windows there are some nasty stuff here. But I never used them.

    Eep. Yeah, probably much safer/smarter to go without the system calls. Didn't know how though.

    humm ok well i was going thru soem stuff for windows,
    and apparently you can encrypt a folder with a user key,
    its a windows capability so maybe youd like to do that?
    if you are interested in it i will go thru the msdn find out the
    information attempt it myself and post the code ?

    Code:
    #include <iostream>
    #include <windows.h>
    
    using namespace std;
    
    int main()
    {
    	//this create a directory
    	if(!CreateDirectory("c:\\NEW Directory\\", NULL))
    	{
    		cout << "Could not create new directory!" << endl;
    	}
    	else
    	{
    		cout << "Directory Created!" << endl;
    	}
    
    	//this encrypt the file, but i dont think it will
    	//do your situation much good, plus i dont know
    	//how to set keys for it, if you even can set a key
    	//for it, but might be fun to play around with.
    	if(EncryptFile("c:\\NEW Directory\\") > 0)
    	{
    		cout << "Encrypt Successful" << endl;
    	}
    	cin.get();
    	return 0;
    }
