C++ :: Creating Bank Accounts Using Classes
Feb 25, 2014
I am creating a bank account using classes. I have created the classes and now implementing them in my main program. I haven't written anything in the withdraw, find acct and all functions except "read account: read_acct()" because i wanna test if it reading the data from my .txt file or not. Dont know whats wrong with the program its not executing. Would let know that i'm new to classes and objects. Following is the code:

I have an assignment to write a program using structures, getting input from a .txt file and output in text file as well. I have written a program that only reads and prints the data. I am trying to test if it works fine or not. I always comment an unnecessary code but still it wont compile. Now whats wrong with this program?
/* Bank Accounts Program */
#include <iostream>
#include <string>
#include <fstream>
#include <cstdlib>//needed to use system() function
using namespace std;
const int MAX_NUM = 50;
void menu();

What I am trying to do is a small program that creates accounts (User name, age,...), and stores it on a CSV file. And later I can search for a user and edit some information about him (example, his age).
Here is my code:
#include <fstream>
#include <iostream>
#include <string>
#include <stdio.h>
#include <io.h>
#include <stdlib.h>
#include <string>
Looking at the "old code" ("void searchaccountold()"), I am sure the problem is on the "while" part ("while (myfile >> name >> age >> money)").
It should work, but it doesnt. I am almost sure the problem lies on the ";"... Because the CSV uses cells, and to pass to the second cell I would normaly need an ";" and in my case I have ">>". I have tryed to change them, to use getline, etc... and didnt work.

I've been working on a project for a few days now, and within this project I need to have a class system that can function similarly to an if statement. The problem I'm having is I can't seem to find any good information on the order in which if statements process the information within it. I understand that if statements process whatever's in parenthesis first, but my question is that when their are several booleans of equal value, for example: "if(x == 1 && y == 2 || 3 == 4 && 4==6)", in what order does it process these true or false statements? (The actual content of the example is superfluous).

For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.
The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.
The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.
What I have so far, and I'm pretty lost;
color.h
Code:
Code:
//color.h
//Color class definition
#include "stdafx.h"
#ifndef COLOR_H
#define COLOR_H
class color {
public:
enum colorType {black, blue, green, cyan, red, magenta, brown, lightgray, nocolor};

I'm am having a few issues with this program, they stem from passing the color.h and .cpp into another .h and .cpp, and frankly getting how those two things really fit together.

The problem that occurs is coming from the I/O I believe. I am creating a bank handling program and I am storing the accounts in a <map> and then I am storing the accounts in a text file. The problem I have is when ever I am closing the application and restarting it and want to read the text file I am getting nothing or I am getting really odd results. In the application it can be that it does not read anything or it could be that I get
Acc nbr: 0
Name: -47000300
Type: 12333993
balance: Å
But in my txt file its perfectly normal. Sometimes when Ive been trying to play around with the code the txt file changes the text to kanji signs. I've created an own implemented class that handles the account for example, deposition, overloading constructor of creating an account, withdraw, returning various information. The attributes are all public.the read file function:
void read_file(){
string name;
int pnbr;
int accNbr;
int balance;

I'm writing a Windows service using WinAPIs and C++. One of the options is that I need to send the system into sleep after all users are logged out. The log-out command is started from the UI (which can notify my service), the problem is knowing how long it takes for all user accounts to be completely logged out before putting the system to sleep.
I first thought to introduce an artificial delay from the moment when the log-out command is issued and before entering the sleep mode, but in a situation when some user account was configured with a roaming profile, the log-out process may well exceed my delay.
how to know if all user accounts are logged out "for sure"?

This exercise should familiarise you with loops, if-then-else statements, and recursion. You will have to design and implement a program that calculates the interest earned on a bank-account. Deadline is the end of Tuesday in week 4.
Interests are compounded; that is, you earn interest on interest. Given a yearly interest rate of say, 6%, you can calculate the total sum available when an initial sum of 4000 pounds is put away for 13 years as follows:
4000 * ( (1 + [6/100])^13 ) = 8531.71 pounds
where the caret symbol denotes 'to the power of'. One way to calculate the power is by repeatedly mulitplying. Ie, you can mulitply 1.06 with 1.06 12 times to calculate 1.06^13.
PART 1
Design and implement a function that raises X to the power Y for a real number X and a positive integer Y. The function must use a while loop.
Design and implement a main program that calculates the sum availble when 1000 pounds has been put away for 25 years with 5 percent interest.
Change the while-loop in the function to a for-loop.

Anyhow, I have a program due Wednesday that is along the lines of the classic Bank Teller simulation using Queue's.
Unlike most of these programs, I have to integrate my own Queue, QueueNode, Teller, and Customer classes. I have attached all of these headers below plus the main file.
Now the error: While I'm sure there are other issues with the code, it will not let me create a new customerQueue (of Queue type) object as such:
Queue<Customer> customerQueue;
The error it is giving me is:
no matching constructor for initialization of 'Queue<Customer>'
Here is my code:
Queue.h:
#ifndef QUEUE2_H_
#define QUEUE2_H_
#include <iostream>
#include "Teller.h"
#include "Queue.h"

I have an odd compiling error. My base class is all delcared and read to go. But I could not figure out how to get my sub classes inherit from it. So I had to make everything public. Even inheriting using the protected inheritance thingy, still could not get them to inherit from that base class.
So I compiled the program, and no other class came back with an error. only my base class. Here is the base class:
#include <iostream>
#include <string>
using namespace std;
class Bankaccount {
[Code] .....
The error I'm getting is saying:
error C2143: syntax error : missing ';' before 'using'
Where is there anything needing a semicolon before using?
'Bankaccount' : 'class' type redefinition
see declaration of 'Bankaccount'
Is it saying this because I don't have any private class members?
'Bankaccount' : base class undefined
But it is defined.
What is the issue with this class? And how can I get it to compile and run?

Following function is from a bank account, when new account is created it won't store it in the array or i guess it does but find_acct function wont be able to find it.
find_acct Function:
int findacct(int acctnum_array[], int num_accts, int requested_account) {
for (int index = 0; index < num_accts; index++)
if (acctnum_array[index] == requested_account)
return index;
return -1;

In this assignment, you are going to write a program that keeps track of the social security numbers (SSN) of customers of a bank. Please notice that we are going to assume that SSN is a four-digit number (e.g., 1234. 0123 is not allowed.). When the program runs, it prompts that the user should enter a 4-digit SSN number to record, or 0 (zero) to exit.
So far I have this:
#include <iostream>
using namespace std;
bool isExist(int ssn, int records[], int numberOfRecords);
int main(){
int ssn = 0;
int records[32];

When the program runs,it has to prompt that the user should enter a 4-digit SSN number to record, or 0 (zero) to exit.
The program also needs to be able to give an error message if a certain number is entered more than once.
After all the numbers have been saved and you finally end it by pressing 0, it needs to be able to output all the entered SSN's.
Here is my code so far :
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
bool isExist(int ssn, int records[], int numberOfRecords);
void listRecords(int records[], int numberOfRecords);

In this program the intention is to create a menu driven program for a pizza restaurant. I have to use a class called Pizza and have to include at least three public functions; one is called SetSize, another one is called Display, and the last one is called ComputePrice. A small pizza is worth $10, a medium is $14, and a large is $17. Each topping is worth 2 dollars. I know that the program runs correctly, but I have doubts over the classes and function actually being utilized correctly or at all.
Program:
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
class Pizza {
private:
int size;
int style;

I'm trying to use multiset with a user defined class "edge". I'm trying to use the multiset as a priority queue, and I've created a "less<edge>" via operator<() overloading.
For some reason, I cannot insert edges into the multiset.
I understand that I might also have to create an "allocator". I got some ideas for creating it at [URL], but still don't know how to define size_type and difference_type.
Attached is my skeleton code, running on Windows 7 (32-bit), under Netbeans IDE, using Cygwin g++ 4.7.3.
How can I get this to work? What is important is that I get a priority queue working with my edges, prioritized by the weight.
#include <iostream>
#include <set> // for multiset
using namespace std; // assume std libraries (i.e. std::XXX)
class edge { // node, weight pair
public:

I've created a base DLL for all my future DLL's, a way of getting version numbers and such and that compiles fine, but I can't add it into a class for a new DLL. All the headers do have an appropriate cpp to define the function declarations (and they compile fine).
All for the base DLL I have:
LibVer.h
Version.cpp
Function.cpp

im creating an address book. One address book contains a ListBox, New User button, Edit User and Remove User button. The first form is suppose to allow you to view the users you've created on the ListBox and you can decide whether you want to remove it, create a new one or simply edit the user. Now The second form simply contains labels and textbox along with a save button. I'm having a bit of issue figuring out the ListBox. I want to be able to create a user and have the user be posted on the ListBox. I read that i must instantiate listbox then simply add it. Now on my form2 i have a for loop that loops through an Array of String were all the users will be created on. How can i call that array of string on to the form1?
Form 1:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
[code].....
EDIT:I just figured out that to call a variable from one form to another you simply instantiate the form then simply call it. PS. must be set to public:
ListBox1 createUser = new ListBox1();
createUser.userString[0];
why doesnt it show the windows when i run without debugging?

n the requirements it says this;
-create a get and set for height, width, length.
-A default parameterized constructor = 1
-A method to resize the box
-A method to get the volume of the box
-A method to convert the object to a string
My Questions:
The 3 parts I am confused by are the default parameter constructor, the re-size the box and the method to convert to string. For the default parameter part I figured making length, width and height = to 1 would work, but I'm pretty sure thats not what I'm supposed to do.
This is the main file
#include "box_class.h"
#include <iostream>
using namespace std;
int main() {
double length;
double width;
double height;
double volume;
