Hey so I have this text file:
1:Vegetarian Dishes:Lettuce:1.99
2:Vegetarian Dishes:Tomato:0.99
3:Drinks:Water:0.5
4:Meat Dishes:Burger:4.99
5:Fish Dishes:Fishes:5
6:Drinks:Coka cola:2.5
7:Drinks:Fanta:1.2
8:Drinks:Absolut:12.99
9:Drinks:Wiskey:9.99
10:Vegetarian Dishes:Lemon:0.99
11:Vegetarian Dishes:Green:2.99
12:Meat Dishes:Pizza:4.99
13:Fish Dishes:Fishes2:5.99
14:Drinks:Milk shake:4.99
15:Vegetarian Dishes:Vegan Sandwich:3.99
and i have objects of Dish class, so I want to read the file and add each dish to a Dish object.
Then i have an array of Dishes. Its supposed to store _itemNo:category:description:price.
Below is my code.
The problem is that it doesn't read the file correctly. Do you see any problems?
Code:
Dish::Dish() { }
Dish::Dish(int itemNo, string category, string description,
double price): _itemNo(itemNo), _category(category),
_description(description), _price(price) { }
void Dish::displayDish(void){
cout << setw(15) << left << _itemNo << setw(30) << left << _category
<< setw(45) << left << _description << _price << endl;
}
DishDb::DishDb(): _nElems(0) { }
void DishDb::addDish(int itemNo, string category, string description,
double price){
_menu[_nElems] = Dish(itemNo, category, description, price);
_nElems++;
}
void DishDb::display(){
int i;
cout <<setw(40) << "MENU" << endl << endl;
cout << "Item No" << setw(15) << "Category" << setw(30)
<< "Description" << setw(40)<< "Price" << endl << endl;
for(i = 0; i < _nElems; i++){
_menu[i].displayDish();
}
}
int main(){
/*Select file name for the bills to be stored in*/
string transFilename;
cout << "Enter today's transaction file name: ";
cin >> transFilename;
/*Load the menu*/
/*Adding each dish object into the _nenu array*/
/*Couldn't make this part object oriented*/
DishDb ddb;
string fileName;
int itemNo;
double price;
string description;
string category;
int i;
int numOfDishes = 0;
cout << "Enter file name: ";
cin >> fileName;
ifstream inFile(fileName);
while(i<15){
inFile >> itemNo;
getline(inFile, category, ':');
getline(inFile, description, ':');
inFile >> price;
numOfDishes++;
Dish(itemNo, category, description, price);
ddb.addDish(itemNo, category, description, price);
i++;
}
ddb.display();
inFile.close();
/* while(inFile >> itemNo && getline(inFile, category, ':') &&
getline(inFile, description, ':') && inFile >> price){
numOfDishes++;
Dish(itemNo, category, description, price);
ddb.addDish(itemNo, category, description, price);
}
*/
cout << endl << "Menu was loaded.";
return 0;
}
I've tried 2 ways of reading the file. With the first i was just checking if the file was beging read correctly but its not.
The following code should work for you:
int main() {
std::ifstream file("dishes.txt");
std::string temp, snum, category, description, sprice;
while (std::getline(file, snum, ':') &&
std::getline(file, category, ':') &&
std::getline(file, description, ':') &&
std::getline(file, sprice)) {
// Do whatever you want with:
// * snum (must convert to integer)
// * category
// * description
// * sprice (must convert to float)
}
}

I am working on this problem for a college course and I'm unsure why it isn't working. I thought I had everything setup correctly, but when I try running the program the file won't open on the first attempt at inputting the file name and when I input it again I get an "Exception Thrown" error in the "xmemory" part that I have no idea what any of it means.
The input file that the program is taking data from is just a text file with the following data:
201742 Sponge Bob 82.6
201701 Patrick Star 14.1
201753 Squidward Tentacles 85.43
201744 Sandy Squirrel 75.61
201700 Plankton Plank 100.0
The final output of the program should display the highest and lowest grade with the students first and last name, the average score, and the number of students tested. Any help would be much appreciated.

The program is supposed to read the file and also allow the user to write to it. After inputting a valid employee ID it pops up the menu allowing the user to enter what they want to change. After inputting those changes and closing the file, it doesn't update the file. It still shows the same values from before.
You can do some thing like,
This code copies Line by line from old file to a tempfile. When you find the line which you want to update, change it with your line and copy it to the tempfile. Then finally copy all data from tempfile to file and delete tempfile

i am used name and id only for simplicity
(OR)
you can use like this also,But this code did not use tempfile. it replaces the new content directly in the file.

are "seekp" & "seekg" interchangeable?

I'm running into an issue where my function will not do anything. It will compile, but there is no output. The thing is when I take out the vector sPay from all the parts it works perfectly fine. Any suggestions as to why that one part isn't working? From my limited knowledge it should work perfectly fine, however I can't figure out what would be causing this.
My example text file is
Alan
WakeField
IT GUY
T2034
40
15
1
Hourly
0.00
Your input file does not match your reading code. There are 9 values in the file that you have shown, but your code is attempting to read only 8 values.
When readIn() gets to this code:
iFile >> dTemp;
sPay.push_back(dTemp);
It attempt to read a double but the file has Hourly instead, so the read fails.
So, either remove the Hourly line from the file, or else add a call to iFile >> sTemp to read that line.
Also, the parameters string sTemp, double dTemp, and int iTemp should be declared as local variables instead of as input parameters.
Also, readIn() is not doing any error handling. Your main() code makes an invalid assumption that the vector of first names exactly matches the size of the other vectors, but readIn() does not guarantee that.
And lastly, checking eof() before you have read anything is wrong. The stream's eofbit flag is not updated until a read operation attempts to read past EOF.
You should consider re-writing this code. For example, try something more like this:
#include <iostream>
#include <string>
#include <fstream>
#include <vector>
struct Employee
{
std::string fName;
std::string lName;
std::string title;
std::string eID;
double hoursWorked;
double wage;
int deductions;
std::string wageType;
double sPay;
Employee() :
hoursWorked(0), wage(0), deductions(0), sPay(0)
{
}
};
void check(std::ifstream &iFile)
{
if (!iFile.is_open())
{
std::cout << "Data file not found or unable to open!" << std::endl;
std::system("pause");
exit(1); // exit the program.
}
}
void readIn(std::ifstream &iFile, std::vector<Employee> &employees)
{
std::ios_base::iostate oldstate = iFile.exceptions();
iFile.exceptions(std::ifstream::badbit | std::ifstream::failbit);
try
{
do
{
Employee emp;
iFile >> emp.fName;
iFile >> emp.lName;
std::getline(iFile, emp.title);
iFile >> emp.eID;
iFile >> emp.hoursWorked;
iFile >> emp.wage;
iFile >> emp.deductions;
iFile >> emp.wageType;
iFile >> emp.sPay;
employees.push_back(emp);
}
while (!iFile.eof());
}
catch (const std::ios_base::failure &)
{
std::cout << "Data file corrupted!" << std::endl;
std::system("pause");
exit(1); // exit the program.
}
iFile.exceptions(oldstate);
std::cout << "completed" << std::endl;
}
int main()
{
std::ifstream iFile("data.txt");
check(iFile);
std::vector<Employee> employees;
readIn(iFile, employees);
int sizeOf = employees.size();
for (int a = 0; a < sizeOf; a++)
{
std::cout << "FName " << employees[a].fName
<< " LName " << employees[a].lName
<< " JobTitle " << employees[a].title
<< std::endl;
std::cout << "EmployeeID " << employees[a].eID
<< " Hours Worked " << employees[a].hoursWorked
<< " << employees[a].wageType << " Wage " << employees[a].wage
<< std::endl;
std::cout << "Deductions " << employees[a].deductions
<< " Salary Pay " << employees[a].sPay
<< std::endl;
std::cout << std::endl;
}
std::system("pause");
return 0;
}
Alternatively, since your data is line-based, you should use std::getline() to read each line, and then use std::istringstream to parse values:
void readIn(std::ifstream &iFile, std::vector<Employee> &employees)
{
std::string sTemp;
std::ios_base::iostate oldstate = iFile.exceptions();
iFile.exceptions(std::ifstream::badbit | std::ifstream::failbit);
try
{
do
{
Employee emp;
std::getline(iFile, emp.fName);
std::getline(iFile, emp.lName);
std::getline(iFile, emp.title);
std::getline(iFile, emp.eID);
std::getline(iFile, sTemp);
if (!(std::istringstream(sTemp) >> emp.hoursWorked))
iFile.setstate(std::ifstream::failbit);
std::getline(iFile, sTemp);
if (!(std::istringstream(sTemp) >> emp.wage))
iFile.setstate(std::ifstream::failbit);
std::getline(iFile, sTemp);
if (!(std::istringstream(sTemp) >> emp.deductions))
iFile.setstate(std::ifstream::failbit);
std::getline(iFile, emp.wageType);
std::getline(iFile, sTemp);
if (!(std::istringstream(sTemp) >> emp.sPay))
iFile.setstate(std::ifstream::failbit);
employees.push_back(emp);
}
while (!iFile.eof());
}
catch (const std::ios_base::failure &)
{
std::cout << "Data file corrupted!" << std::endl;
std::system("pause");
exit(1); // exit the program if the file is corrupted.
}
iFile.exceptions(oldstate);
std::cout << "completed" << std::endl;
}
I went derp for a moment. I forgot to read in the hourly or salaried before going to salary pay.
The program, is basically sussposed to iterate a file containing the elements

what my current program is outputting the phonenumber if firstname and lastname is present in file but if its nothow do i output phone number isnt here my current code.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void lookup_name(ifstream&, string&, string&, string&); // prototype
int main()
{
ifstream myfile;
string name, lastname, phonenumber;
char choice;
do
{
myfile.open("infile.txt");
cout << "What is the First name? " << endl;
cin >> name;
cout << "what is your last name?" << endl;
cin >> lastname;
lookup_name(myfile, name, lastname, phonenumber);
cout << "Do you want to lookup another name<Y/N" << endl;
cin >> choice;
} while (choice == 'Y');
return 0;
}
void lookup_name(ifstream& myfile, string& name, string& lastname, string& phonenumber)
{
string name1, name2, fullname, secondname, dummy;
for (int i = 0; i < 5; i++) {
myfile >> name1 >> name2;
fullname = name1 + name2;
secondname = name + lastname;
if (fullname == secondname) {
myfile >> phonenumber;
cout << phonenumber << endl;
myfile.close();
break;
}
else if (fullname != secondname) {
myfile >> dummy;
phonenumber = dummy;
}
Just return whether you found it or not from your lookup function
int lookup_name(ifstream& myfile, string& name, string& lastname, string& phonenumber)
{
string name1, name2, fullname, secondname, dummy;
for (int i = 0; i < 5; i++) {
myfile >> name1 >> name2;
fullname = name1 + name2;
secondname = name + lastname;
if (fullname == secondname) {
myfile >> phonenumber;
cout << phonenumber << endl;
myfile.close();
return 1;
}
else if (fullname != secondname) {
myfile >> dummy;
phonenumber = dummy;
}
}
return 0;
}
Then use the return value
if ( ! lookup_name(myfile, name, lastname, phonenumber) ) {
cout << "Nope, didn't find it!" << endl;

Any help would be appreciated. All I'm trying to do is ask for user input, do some calculations and print the results in a file. I thought that my code was correct but when I run my program, I get nothing. Here is my code. Not looking for an answer, just for any tips to lead me in the right direction. Thanks.
#include<iostream>
#include<fstream>
#include<string>
using namespace std;
class Employee{
private:
int id;
int job_class;
int years_service;
int Ed;
float salary;
public:
void getData(ifstream&);
void computation(int job_class, int years_service, int Ed);
void printout(ofstream&);
};
void Employee::getData(ifstream& infile){
infile >> id >> job_class >> years_service >> Ed;
}
void Employee::computation(int job_class, int years_service, int Ed){
int basePay = 800;
float jobresult, Yearresult, Edresult;
if(job_class == 1){
jobresult = .05;
}
if(job_class == 2){
jobresult = .10;
}
if(job_class == 3){
jobresult = .15;
}
if(years_service <= 10){
Yearresult =.05;
}
if(years_service > 10){
Yearresult = .05;
}
if(Ed == 1){
Edresult = .00;
}
if(Ed == 2){
Edresult = .05;
}
if(Ed == 3){
Edresult = .12;
}
if(Ed == 4){
Edresult = .20;
}
salary = basePay + jobresult + Yearresult + Edresult;
//cout << salary;
}
void Employee::printout(ofstream& outfile){
outfile << "ID: " << "Salary " << endl;
outfile << id << salary;
}
int main(){
Employee emp; //created an Employee object
string input;
int id;
int job_class;
int years_service;
int Ed;
int basepay = 800;
cout << "Enter id" << endl;
cin >> id;
cout << "Enter job_class" << endl;
cin >> job_class;
cout << "Enter years of service" << endl;
cin >> years_service;
cout << "Enter education" << endl;
cin >> Ed;
ifstream inFile;
ofstream outFile;
//getline(cin, input);
inFile.open("example.txt");
outFile.open("examplee.txt");
//inFile.open(input);
std::string r = std::to_string(id); //converted id to string
inFile.open(r);
getline(cin, r);
std::string s = std::to_string(years_service);
inFile.open(s);
getline(cin, s);
std::string t = std::to_string(years_service);
inFile.open(t);
getline(cin, t);
std::string u = std::to_string(Ed);
inFile.open(u);
getline(cin, u);
if(inFile.is_open()){
emp.getData(inFile);
inFile.close();
}
outFile.open(r);
if(outFile.is_open()){
emp.computation(job_class, years_service, Ed);
float sal = basepay + job_class + years_service + Ed;
outFile << "ID " << "Salary " << endl;
outFile << id << sal;
outFile.close();
return 0;
}
}
What exactly are you trying to do with things like this?
std::string r = std::to_string(id); //converted id to string
inFile.open(r); /*Opens a file whose name is <id> ???*/
getline(cin, r); /*Overwrites the contents of r and does nothing??? */
Your entire program is fairly confusing. My best guess as to the (main) problem is that you aren't writing anything to inFile at all. Those 12 lines after outFile.open("examplee.txt") seem like they are trying to accomplish the following:
inFile << id << ' ' << job_class << ' ' << years_service << ' ' << ED << '\n';
Also, although I'm guessing this is for debugging purposes, but many of your methods do nothing or are unused. For example, you use emp.computation(job_class, years, ED) but after that you don't use emp at all in any way. And the three lines after that seem to mimic the behavior of Employee::computation and Employee::printout.
I suggest you carefully consider the specific steps you're trying to take, then think about the purpose of methods like getline and fstream::open, and ask yourself "Does this accomplish the task I had in mind?". Because I'm really struggling to understand what you are trying to do when I read this code.
