railwaycli's Issues

includes and namespace

includes and namespace

RailwayCli/main.cpp

Lines 1 to 6 in 021ebb1

#include<iostream>
#include<fstream>
#include<string>
#include<bits/stdc++.h>
using namespace std;

the #include<bits/stdc++.h> used for transform(... ::tolower) function
like this example

RailwayCli/main.cpp

Lines 148 to 154 in 021ebb1

cout << "Enter Passenger name: ";
getline(cin, person.name);
transform(person.name.begin(), person.name.end(), person.name.begin(), ::tolower);
cout << "Enter Passenger family: ";
getline(cin, person.family);
transform(person.family.begin(), person.family.end(), person.family.begin(), ::tolower);

Input: 3. Check Ticket

}

HaveTicket() and ShowTicket() on #5

Input: 1

Task 1. Reserve a Seat

RailwayCli/main.cpp

Lines 301 to 305 in 021ebb1

case e1:
{
AddSeat();
break;
}

so, we need to reserve a new seat between 10 compartments & 6 Seats on every of them

RailwayCli/main.cpp

Lines 140 to 181 in 021ebb1

void AddSeat()
{
cout << endl;
Person person;
ofstream File("Train.txt", ios::app);
ifstream InFile("Train.txt");
cin.ignore();
cout << "Enter Passenger name: ";
getline(cin, person.name);
transform(person.name.begin(), person.name.end(), person.name.begin(), ::tolower);
cout << "Enter Passenger family: ";
getline(cin, person.family);
transform(person.family.begin(), person.family.end(), person.family.begin(), ::tolower);
string fullName = person.name + ", " + person.family;
if (HaveTicket(fullName))
{
cout << "\n-- Passenger Have Ticket Already! --" << endl;
ShowTicket(fullName);
}
else
{
if (Availabe(0) != "0")
{
person.compartment = Availabe(0);
person.seat = Availabe(1);
File << person.name << ", " << person.family << ", " << person.compartment << ", " << person.seat << endl;
File.close();
cout << "\n-- Ticket Added Successfully! --" << endl;
ShowTicket(fullName);
}
else
{
cout << "\n-- Train Was Full! --\n\n\n";
}
}
}

i create an object of Person for working with input data
first we most initial an object from ifstream and ofstream on the fstream Library

give person.name & person.family from client and make those ::tolower

put name and family together and make new string fullName
maybe you question why we do that??
for better query on database Train.txt
cause data save like this:

sara, irani, 9, 6 
ehsan , reziea, 10, 1

when we gonna know about this name is record on database or not
we must use this format <person.name>, <person.family> for search

then pass fullName to bool HaveTicket(string searchContent) function

RailwayCli/main.cpp

Lines 16 to 34 in 021ebb1

bool HaveTicket(string searchContent)
{
ifstream inFile("Train.txt");
string line;
bool state = false;
while (getline(inFile, line))
{
if (line.find(searchContent) != string::npos)
{
state = true;
return true;
}
}
if (!state)
{
return false;
}
}

that a bool function, so, return true false value
if data base have same name and family call another method whose name void ShowTicket(string personFullName)

RailwayCli/main.cpp

Lines 82 to 120 in 021ebb1

void ShowTicket(string personFullName)
{
ifstream inFile("Train.txt");
string line;
while (getline(inFile, line))
{
if (line.find(personFullName) != string::npos)
{
cout << "---------TICKET----------" << endl;
int countComma = 0;
cout << "Name: ";
for (int i = 0; i < line.size(); i++)
{
if (line[i] != ',' && line[i] != ' ')
{
cout << line[i];
}
if (line[i] == ',')
{
countComma++;
cout << endl;
if (countComma == 1)
{
cout << "Family: ";
}
if (countComma == 2)
{
cout << "Compartment: ";
}
if (countComma == 3)
{
cout << "Seat: ";
}
}
}
cout << "\n-------------------------\n\n\n";
}
}
}

that output something like this

-- Ticket Added Successfully! --
---------TICKET----------
Name: sara
Family: irani
Compartment: 1
Seat: 1
-------------------------

give different name, family on reserve compartment

  • when reserve a compartment give 6 name and family for 6 seats on compartment when available

    RailwayCli/main.cpp

    Lines 183 to 226 in 021ebb1

    void AddCompartment()
    {
    cout << endl;
    Person person;
    ofstream File("Train.txt", ios::app);
    ifstream InFile("Train.txt");
    cin.ignore();
    cout << "Enter Passenger name: ";
    getline(cin, person.name);
    transform(person.name.begin(), person.name.end(), person.name.begin(), ::tolower);
    cout << "Enter Passenger family: ";
    getline(cin, person.family);
    transform(person.family.begin(), person.family.end(), person.family.begin(), ::tolower);
    string fullName = person.name + ", " + person.family;
    if (HaveTicket(fullName))
    {
    cout << "\n-- Passenger Have Ticket Already! --" << endl;
    ShowTicket(fullName);
    }
    else
    {
    if (AvailabeCompartment() != "0")
    {
    person.compartment = AvailabeCompartment();
    for (int seatsI = 0; seatsI < 6; seatsI++)
    {
    person.seat = Availabe(1);
    File << person.name << ", " << person.family << ", " << person.compartment << ", " << person.seat << endl;
    }
    File.close();
    cout << "\n-- Tickets Added Successfully! --" << endl;
    ShowTicket(fullName);
    }
    else
    {
    cout << "\n-- Don't Have Empty Compartment! --\n\n\n";
    }
    }
    }

Input: 4

Input: 4. Ticket Refund

RailwayCli/main.cpp

Lines 325 to 330 in 021ebb1

case e4:
{
string fullName = GiveFullName();
RefundTicket(fullName);
break;
}

GiveFullName on #13

void RefundTicket(string fullName)

RailwayCli/main.cpp

Lines 228 to 261 in 021ebb1

void RefundTicket(string fullName)
{
string line;
string newFile = "";
bool state = false;
ifstream InFile("Train.txt");
while (getline(InFile, line))
{
if (line.find(fullName) == string::npos)

ShowTicket(fullName);

}
InFile.close();
ofstream File("Train.txt");

File.close();
if (state)

in switch case statement, don't worry about e1, e2 ,e3, ... and so on.
when we use normally 1, 2, 3, ...
and client is type like 53 get stuck at a infinite loop and crash
even though we use default: key word on last case,
so, we need two use something different for this issue
use enum!
and translate elements to numbers like this:

RailwayCli/main.cpp

Lines 263 to 281 in 021ebb1

enum string_code
{
e1,
e2,
e3,
e4,

if (inString == "2") return e2;
if (inString == "3") return e3;

else return other;

Input 1. Reserve a Seat

RailwayCli/main.cpp

Lines 301 to 305 in 021ebb1

case e1:

so, we need to reserve a new seat between 10 compartments & 6 Seats on every of them

RailwayCli/main.cpp

Lines 140 to 181 in 021ebb1
