Struct with arrays in functions

  Posted 14 January 2009 - 07:26 AM

I'm working on an assignment its been awhile since i have been coding and need a little help, also i have yet to ever do struct before

Write a program that uses a structure to store the following data about a customer account:

* Name (full name in one variable)
* Address (full street address in one variable)
* City, State and Zip
* Telephone number
* Account balance
* Date of last payment

The program should use an array of at least 20 structures. It should let the user enter data into the array, change the contents of any element and display all the data stored in the array. The program should have a menu-driven interface and use functions as appropriate.

Input validation: when the data for a new account is entered, be sure the user enters data for all the fields (no empty fields). No negative account balances should be entered.

Help need with:

1) calling the function to display just the balance.
2) calling the function just too allow the person edit the balance.
-I dont know how to call a different customer (i.e. 2 customers they want to edit #2)

#include <cstdlib> #include <iostream>  using namespace std; void Acc(string , int, int AcArray[]); void Load(string, string, int AcArray[]); void Display(int AcArray[]); void menu(); double CBalance(int AcArray[]); void question();  struct account 	{ 		char name[30];	  //customer name 		char address[30];   // address 		char city[16];	  //city 		char state[2];	// State two letters 		char zip[5];	  // zip  5 numbers 		char tele[12];	 // telephone number 12 characters 		double account;	   // account total 		char date[20];	  // date  		int total[30];	  // total array length	    	};  int main(int argc, char *argv[]) { 	int AcArray[30];    //menu; 	 	 	system("PAUSE"); 	return EXIT_SUCCESS; }  void menu { 	int choice;  	 	cout << "Welcome to you account management software, which action would you like to take?" << endl; 	cout << "Press 1. Enter a new account." << endl; 	cout << "Press 2. Display current account balances." << endl; 	cout << "Press 3. Edit current accounts." << endl; 	cout << "Press 4.

Is This A Good Question/Topic? 0

Hi I changed some things in your code, see the comments for more detail.

struct account     {         //  Cnanged all char's to strings         string name;      //customer name         string address;   // address         string city;      //city         string state;    // State two letters         string zip;      // zip  5 numbers         string tele;     // telephone number 12 characters //        double account;       //  account isn't a double, it is declared as a struct so remove it         char date[20];      // date  //        int total[30];      // total array length should't be here neither, but if you want it, don't use it as an array         int balance;    //  Added balance, as it is a requirement for the assignment and also quite hard to display if it itsn't here ;)/>     };  void editBalance( account AcArray[], const int MAXACCOUNTS ) {     for( int i = 0; i < MAXACCOUNTS; i++ )         AcArray[i].balance = i;         //  This will edit the balance of each account }  void displayBalance( account AcArray[], const int MAXACCOUNTS ) {     for( int i = 0; i < MAXACCOUNTS; i++ )         cout << AcArray[i].balance;  //  This will print the balance of each account }  int main(int argc, char *argv[]) {     const int MAXACCOUNTS = 30;            //  Added a variable to use trought the program     int account AcArray[MAXACCOUNTS];  //  Add 'account' here    //menu;          editBalance( AcArray, MAXACCOUNTS );      displayBalance( AcArray, MAXACCOUNTS );               system("PAUSE");     return EXIT_SUCCESS; }            

EDIT: Was in a hurry since I'm at work atm so I just tossed it togeather real quick, hope it works. Also didn't go trough you entire code fully in my example. You'll need to change quite a bit in the rest of your code for it to compile but I hope this will help you a bit along the road

Since you are using C++ and C++ strings now ... you might as well go for a vector container to hold each struct (instead of an array of structs) ...

See the simple example below ...

Or ... since ...

// The program should use an array of at least 20 structures.
// It should let the user enter data into the array, change
// the contents of any element and display all the data stored
// in the array.

You could do something like this ... ( as a shell to get started )

#include <iostream> #include <string> #include <iomanip> using namespace std;  const int MAX = 20;  struct Data {     string name;     string id;     int balance; // in cents };  bool more();  int main() {     // create a empty array like this     Data myBank[MAX];     int i=0;     do     {         cout << "Name    : ";         getline( cin, myBank[i].name );         cout << "ID      : ";         getline( cin, myBank[i].id );         cout << "Balance : ";         cin >> myBank[i].balance;         if( !cin.good() )         {             cin.clear();             cin.sync();             continue;         }         cin.sync();         ++i;              }while( more() && i<MAX );           // show elements in each record ...     for (int j=0; j<i; ++j )     {         cout << setw(4)<< j+1 << " "              << left << setw(20) << myBank[j].name << " "              << setw(8) << myBank[j].id << " "              << right << setw(8) << myBank[j].balance              << endl;     }     cout << "\nPress 'Enter' to continue ... " << flush;     cin.sync();     cin.get();            }  bool more() {     cout << "More (y/n) ? ";     int reply = cin.get();     return !(reply=='n' || reply=='N'); }

Thanks for the help here is what i have been able to complete. I'm having some problems debugging the program tho =/

I not sure if you 'appreciate the point' of giving you a 'shell of WORKING code' to start out from ... ?

It is helpful to add only ONE new function at a time and compile and test that function ... and to get that all debugged and tested before you add any more.

This way ... you will limit where you need to look in your code for problems ... as to why it won't now compile ... or if it compiles ok ... why it gives the 'not so funny' output it does now.

Please post your last code that compiled and produced the output that you desired ... and then describe what (next) function(s) you wish to add and the code that you have for them so far ...

Shalom,
David

I had it working up until i made getting the info into a function and made the Menu function

#include <iostream> #include <string> #include <vector> #include <iomanip> using namespace std;  struct Info { 	string name; 	string address; 	string city; 	string state; 	string zip; 	string tele; 	double balance; // in cents 	string date; };  bool more(); void start();  int main() { 	menu();    	system("pause");		    }   bool more() { 	cout << "More (y/n) ?

Re: Struct with arrays in functions

Posted 18 January 2009 - 04:29 PM

P.S.

One way to structure your Main Bank, where each client may have several accounts ...

would be to use a vector of vectors ... (or perhaps a linked list of vectors ...)

and just push_back (or append) each new 'mini-bank' vector that holds the accounts for one customer ... onto the company NEWBank vector (or list) of vectors of your struct's ...

But first ... get the program working as you want it to ... for just one customer. (and then you can go for the 2 or 3 or so ... customers modifications ... that may take a fair bit more work and a quite a bit more time.)

Shalom,
David
