I am working on a project that is like a banking system and needs to include making a withdrawal, transaction, deposit, query, and transaction.
Code:
#include <stdio.h>
//#define true
//#define false
//assume there is money in the account. $10,000
void deposit(){
[Code] ....
So I'm doing a kind of banking system. Atm I've got the user able to create an account and set the balance of it, which is written to a .txt file. However, I would like the user to be able to enter their account no. and the program to cout the account info on the screen. I will be adding more to the program later, but until I work out how to search for values in a .txt file, and print out values on that line I'm a bit stuck.
Code:
Main.cpp -
#include <iostream>
#include "create_account.h"
#include <fstream>
using namespace std;
int menuin;
int main() {
create_account creataccObj;
[Code] .....
Sample .txt file -
// Account_no - Balance //
1001 140500
1002 150600
1003 18600
Im building a banking system. in my create_account it asks for account address and phone number as well as other questions. When I go to my Show account info (balance inquiry) I notice its not getting the right address as well as phone number. its showing "garbage".
Code:

I'm supposed to build a banking simulation program around the BankAcct class, which provides the following service: create new account with unique account number (maximum 5 accounts created in a single test running); deposit/withdraw; print information of all existing account. I was running a test program with only 2 services first, namely creating new account and depositing, but the program just keep on crashing and I couldn't figure out why.

I just started my task with Ordering system. what should I use if I'm going to ask the user if he wants to exit the system, he will press(zero)0 to exit the program and press Y(uppercase or lowercase) to continue?

how to invoke a UNIX command within a program
I found this:
dd if=/dev/urandom of=myrandom bs=100 count=1
and I found this:
dd if=/dev/zero of=mytestfile.out bs=1 count=0 seek=1G
I want to call this command, by using the command line and typing Generate or something to that effect.
Basically, I want to be able to build random size files, content isn't important to me at this time.
I know there has to be a system call to pause (not system("pause") execution of a program for a few seconds. I would like to give the illusion that my program is 'thinking' rather than just spit out the result as soon as the user has hit the enter key.

I'm writing a program to turn the two commands "gunzip file.tar.gz" then "tar -xvf file.tar" into "x file.tar.gz", but I've ran into a problem I can't find a solution to, here are the outputs I get depending on if I use a gunzip -f flag in my system() call or not:
if I use: (void)system("gunzip ", store );
> x file.tar.gz
gzip: compressed data not read from a terminal. Use -f to force decompression.
type: gzip -h
store 1: file.tar.gz
tar: option requires an argument -- 'f'
[code]....
I don't know if the problem is something to do with my code or something to do with gunzip and if it is to do with gunzip if I can even solve it with my code? I've tried for a while to find more info and read the gunzip man file, ran "gunzip file.tar.gz" outside of my program and found that it works normally producing file.tar so I suspect the problem is related to system()?

I have to write a program that simulates a handheld gaming system. a system can have power toggled so its either on or off. when the system is on, its volume level can be raised or lowerd. a system has minimum volume level of zero and a maximum volume level of 10. a system stores games.
// simple game menu
//simulates a handheld gaming system
using namespace std;
class Game {
public:
Game(int GameNumber = 3, int volume = 10);
[Code] .....
I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?

This is my code, when my pintrials = 0, my system cannot terminate but go through the option menu below.
So, as far as I can tell, this code should run a system command from the C++ program:
system("ping 192.168.1.2 /t /l 32768");
However, I just keep getting a "system Was not declared in this scope" error message. Is there something wrong with this?
Here's the objective of the program: "Instead of using ABCDEFGHIJ to order letters use DCBAJIHGF go order. The program should determine which 4-letter word is larger of two based on this new ordering system."
Not even sure how to start with this problem , how would I go about defining my own ordering system?
Computerized GPA Evaluation System using Array
You are required develop a computerized GPA evaluation system of your class using array. The basic idea is to calculate the GPA (Grade Point Average) of each subject and then calculate the GPA of whole semester of all the students of the class and on the basis of that GPA calculate the grade and remarks of each student of the class. Suppose that the total students of the class are 50. Your system must also provide the facility of the following:
1.Searching a student result according to his/her roll number.
2.Updating the obtained marks of the students in case of any mistake in entering marks.
3.Display the result of student who is the topper of the class
4.Display the result of the student who got minimum CGPA out of the class.
5.Display how many number of students got greater than or equal to 3.0 CGPA.
6.Display how many number of students got greater than or equal to 2.00CGPA and less than 3.00.
7.Display the total number of students who got A grade in the semester.
8.Display the total number of students who got B grade in the semester.
9.Display the total number of students who got C grade in the semester.
10.Display the total number of students who got F grade in the semester.
Detailed Description:
You are required to take the student’s marks for four subjects (Programming fundamentals, Calculus, English and Computing) as input from the user at runtime. After that calculate the GPA of each subject and the whole semester. Assume that total marks of a subject are 100 and each subject is of 3 credit hours except programming fundamentals. Programming fundamentals subject has 4 credit hours.
Complete Assessment system is given below in the table:
S.#Percentage (%)GradeGPARemarks
185-100A4Excellent
280-84A-3.75Very Good
375-79B+3.50Good
470-74B3.0Satisfactory
565-69C+2.50Above Average
660-64C2.0Average
755-59D+1.50Pass
850-54D1.0Just Pass
9Below 50F0Fail
Table: Assessment Scheme
•Percentage of a subject = (obtained marks / total marks) * 100. Percentage works to find the grade of the student.
•GPA of whole semester = multiply GPA of each subject according to the percentage of obtained marks by the number of credit hours for that course, sum up the GPA of all the subjects, and then divide this sum by the total number of credit hours taken in semester.
For example suppose the GPA in subject X is 2.5, in subject Y 2.6, and in subject Z is 3. Assuming that each subject is of 3 credit hours then GPA of whole semester will be calculated as:
GPA= (3 * (2.5 + 2.6 + 3)) / 9
GPA= 2.7
On the basis of Semester GPA, you have to give grade and remarks to the student. You have to study the above table for other types of remarks according to grade.
•If a student has less than 50 marks in a subject, a message should display that “you have to repeat this subject “.

I wanted create a Reminder Systems for my Project
So Scenario is like this,A Gym has owned a Software to maintain record of employee and customer, everything is ready now only reminder system is to be made. Reminder system is like for example if customer comes to gym and inquires about plan and fees and says call back him at so and so time, so receptionist will require reminder system to alert him at the time given by customer for call back.
What i have done
1.Created a Listview to show reminder list, and created two button ADD reminder and DELETE reminder When reminder is added following things are added in Reminder table in Database
i.ID
ii.Title
iii.Message
iv.Time
v.Date
2.when i display the reminder table in reminder listview, the order will be in (Date, time)asecnding order.
---Till here everything is done---
Now i am confused here, lets take example The first Reminder in Listview is around 3.00 clock, when the time is reached i want to show message that "call back this customer".
So to do this i was thinking of using timer and on each tick compare Current time with Reminder time, if equals display message, but this method is inefficient it can freeze my UI.
The Alternate way i was thinking to run this timer inside Background worker as it would create a different thread there will be no issue with my application.
