Concepts of OOP

OOP CONCEPTS

Object-Oriented Programming is a paradigm that provides many concepts such as inheritance, Abstraction, Encapsulation, polymorphism, etc.

 What is Abstraction?
Abstraction is a process where you show only “relevant” data and “hide” unnecessary details of an object from the user.

 What is Encapsulation?
 Encapsulation simply means binding object state(fields) and behavior (methods) together. If you are creating a class, you are doing encapsulation.

 What is Polymorphism?
Polymorphism is an object-oriented programming feature that allows us to perform a single action in a different way.

 What is Inheritance?
When one object acquires all the properties and behaviors of a parent object, it is known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism.

 What is Class?
Collection of objects is called class. It is a logical entity. A class can also be defined as a blueprint from which you can create an individual object. Class doesn't consume any space.

 What is Object?
Any entity that has state and behavior is known as an object. For example a chair, pen, table, keyboard, bike, etc. It can be physical or logical. An Object can be defined as an instance of a class.

C program that contains a string XOR each character in this string with 0 ,127

By -
Write a C program that contains a string (char pointer) with a value \Hello World’. The program should XOR each character in this string with 0 and displays the result. Program: #include<stdlib.h> main() { char str[]="Hello World"; char str1[11]; int i,len; len=strlen(str); for(i=0;i<len;i++) { str1[i]=str[i]^0; printf("%c",str1[i]); } printf("\n"); } Q.2 Write a C program that contains a string (char pointer) with a value \Hello World’. The program should AND or and XOR each character in this string with 127 and display the result. PROGRAM: #include <stdio.h> #include<stdlib.h> void main() { char str[]="Hello World"; char str1[11]; char str2[11]=str[]; int i,len; len = strlen(str); for(i=0;i<len;i++) { str1[i] = str[i]&127; printf("%c",str1[i]); } printf("\n"); for(i=0;i<len;i++) { str3[i] = str2[i]^127; printf("%c",str3[i]); } pri

Queue in Data Structure(DS)

Queue Queues are data structures that follow the First In First Out (FIFO) i.e. the first element that is added to the queue is the first one to be removed. Elements are always added to the back(rear) and removed from the front. Think of it as  a line of people waiting for a bus. The person who is at the beginning of the line is the first one to enter the bus.   Basic features of Queue Like a stack, the queue is also an ordered list of elements of similar data types. A queue is a FIFO( First in First Out ) structure. Once a new element is inserted into the Queue, all the elements inserted before the new element in the queue  must be removed, to remove the new element. In a simple queue, there is a disadvantage after deleting element we cannot insert the element in the queue because of insertion  is possible from the rear but deletion is performed from the front.                                           insertion                                     ------------------
