Why OOP?

-
Just as the name suggests this programming method uses objects. OOP aims to implement properties like inheritance, hiding, polymorphism, encapsulation, etc in programming. The main aim of OOP is to clamp together all the data and the functions that bind them so that no other part of the code can access a particular data except that prescribed function. It basically helps us to write more efficient code using way lesser lines than generally needed. 

OOP is an archetype to design a program using classes and objects, it basically simplifies software development and maintenance. It is a method of solving enigmatic problems by breaking them into smaller problems using objects. Before OOP, programs were written like a procedure, in a step by step sequence, they were like a long list of instructions. But the OOP is about creating objects and classes that will interact with each other and perhaps form some kind of hierarchy among themselves for more efficient code.


Advantage of OOP over Procedure-oriented programming language:

  • In OOP we can easily develop and change the code easily and efficiently by just editing the classes and the functions used. Whereas in Procedural oriented programming it is quite cumbersome to make changes, rather many generally opt to replace the entire code itself.
  • In OOP we can hide the data whereas in procedural oriented programming if the data is declared globally as a global variable it can be accessed from anywhere.
  • In OOP we can simulate real-world events easily. Solutions to real-world problems can be easily provided using a data flow model in OOP.
  • OOP concept of Inheritance is useful for accessing base class properties into the derived class. So, this increases code reusability and reduces code length.
  • OOP concept of Encapsulation is a data hiding property within a class so that a particular data member can remain private.
  • OOP concept of Polymorphism which uses virtual methods which is useful in overriding class properties and methods.

Why have we chosen C++ as a platform to implement our project?


Basically, throughout our Engineering course, we have been familiar with C++. Keeping its technical aspects aside we as students have developed a form of an attachment to this language and so there is somewhat of personal bias towards this programming language. Moving on to our benefit C++ is generally preferred over other languages because it supports all the basic general features of OOP in an easy way. In C++ programs are expandable so more features can easily be added and the existing features can be easily modified. This saves time in the software development part. Moreover, all the points mentioned in the above subheading in advantages of OOP are all followed by C++ that are Classes, Inheritance, Encapsulation, etc. so let's not mention them again. So that is particularly why we mutually agreed on C++ to be our platform for this project.

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
