Vacancy Status and Passenger Information Display System

-

1.        Vacancy status based on priorities:
In the previous blog, we have seen priority function which is based on age and gender criteria. Age and gender are assigned using given information by the user. In the first part of this blog, we are going to discuss the vacancy status display function which is based on priorities.
The most important concept in object-oriented programming which we have used in this part is nothing but inheritance. The function named as ‘status_display’ which is inherited from passenger class which derived from base class is used for showing the vacancy status in a particular train. In the priority function, we assigned four priorities and the maximum limit of each priority is three.
Now to see the vacancy status the choice you have to pick is the fourth option. So, to see the vacancy status table you have to press 4. So, basically, we have used switch case to call the function when you press the desired option. In the beginning, when there is no reservation i.e when the reservation list is empty, table will show all the priorities will show their maximum limit which is three as shown in Fig. 1. When the reservation process is going on, priority in the particular category decreases with the help of user’s information which is provided at the time of reservation. It is shown in Fig. 2.

1.        Passenger Information Display System:
Passenger Information Systems (PIDS) are digital information systems that display real-time information for passengers at the railway stations. Due to this, they also offer news and entertainment content as well as safety and emergency announcements and much more. In the second part of this blog, we are going to discuss the ‘Rail Display Network’ which is used to display the details of the train as shown in Fig. 3.
Fig. 3 Rail Display Network
 The RDN screens will display information related to arrivals, departures and running status of trains including expected delays and other relevant information like platform numbers, coach guidance and ticket confirmation status, etc. So using the ‘viewdetails’ function, we are going to implement this network with the help of train number, name of the train, destinations, charges per person and time. In this case, if you have to see the details of the train, the choice you have to pick is the fifth option. Hence you have to press 5 to see the details of the trains.
The details look like this:

Do you have a ticket?

Passengers, you have booked a seat in this journey. Can you show us the ticket? Ticket is an essential necessity whenever you travel in a train. So now that your seat is booked we will issue a ticket to you, which will help you travel with us hassle-free. Lets print the ticket! The function printticket() will take the value of head node and print the ticket. void passenger :: printticket(struct node *head) {                 struct node *p=head;                 char name1[20];                 cout<<"\n Enter the name of passenger to print ticket:\n"; The traversal in the list to display registered passengers.                   while(p)     {         cout<<p->name;         p=p->next;     } The strcmp() compares two strings character by character. The names stored in list and the name entered will be compared. Linked list is traversed to match the name.                 while(1)                 {                 if(

It's moderator's Office

Hello! We are back! Let's move one step up. We have discussed the important functions of the passenger class until now. We also discussed the important building blocks of C++ - the overloading and dynamic memory allocation. Let us look at actual implementation now. In this blog, we will be discussing more about the functions of the Moderator class. Moderator is the higher authority class which actually is able to modify the details of trains and can alter the timetable. Let us look at the functions one by one.  As we have discussed in function overloading we have two functions having the same name but different parameters as input. Here is the illustration of a function named add_trains().  class moderator { private: trains *head,*tail; public:     moderator()     {         head = NULL;         tail = NULL;     }     void add_trains();     void add_trains(int a,char *t, char *s,char *d,int c,int h, int m);     void deleteTrains(struct

Dynamic Memory Allocation in C++

-
Image
All the functions of Dynamic memory allocation like malloc, calloc, realloc, free etc. are defined in a header <cstdlib>. These functions are used to allocate and deallocate dynamic memory. Two operators named new and delete are used for allocating and freeing the memory respectively in a better and easier way. Dynamic memory is allocated using ‘new’ operator. The memory which is dynamically allocated using new operator can be freed using ‘delete’ operator. Syntax of new and delete operator is - 1. ptr_var = new data_type; 3. delete ptr_var; 2. ptr_var = new data_type[size]; 4. delete[] ptr_var; Let’s see the use of other memory allocation functions in programming: I. malloc() function: In simple words, malloc means memory allocation. This function allocates memory blocks of given si
