What is the Queue algorithm in the C data structure? 1)Storage for a queue….. Struct intqueue { int *queueAry; int maxSize; int countt; int … Read more
The structure of a C program is typically organized into several parts. Here’s an outline of the key components of a basic C program: 1.Preprocessor Directives These are instructions to the C preprocessor. They usually include library imports or macro definitions and start with #. Common examples: #include <stdio.h> // For input/output functions #include <stdlib.h> … Read more
Algorithm for creation in a Linked List CREATE—In this algorithm, a Linked List of nodes is created. The list is pointed by pointer first, the last node of the list points to NULL., indicating the end of the list. Each node has two parts DATA and NEXT. Let us assume that a linked list of … Read more
The array is also called a constant pointer. This pointer points to the first element of the array. Whenever you create an array, this pointer is automatically created. So, if you assign an array name to a pointer variable, then there is no need to use an address of the (&) operator before the name … Read more
This Java program source code converts temperature from Fahrenheit to Celsius scale. import java.util.*; class FahrenheitCelsius { public static void main(String[] args) { float temp; Scanner inn = new Scanner(System.in); System.out.print(“Enter temperature in Fahrenheit=”); temp= inn.nextInt(); temp = ((temp – 32)*5)/9; System.out.println(“Temperature in Celsius = ” + temp); } } In the above program, you … Read more
Write a program in Java to Swap two digits using a third variable. import java.util.Scanner; class Swapping { public static void main(String args[]) { int first_no, sec_no, third_no; System.out.println(“Enter first_no and sec_no”); Scanner in = new Scanner(System.in); first_no = in.nextInt(); sec_no = in.nextInt(); System.out.println(“Before Swapping\nfirst_no = “+first_no+”\nsec_no = “+sec_no); third_no = first_no; first_no = sec_no; … Read more
In this tutorial, I am going to show you how to take input from users in Java using two different ways. You can follow any method(Scanner, Buffered) according to your convenience. To understand how we get input from users in Java we first must know the following two things : System.out – Java uses System.out to … Read more
In C++, visibility modes refer to the accessibility of class members (such as variables and functions) from different parts of a program. C++ provides three visibility modes: public, private, and protected. These modes control the access levels of class members concerning the outside world and derived classes. Public: Members declared as public are accessible from … Read more
In C++, inheritance is a fundamental concept of object-oriented programming (OOP) that allows you to create a new class based on an existing class, known as the base or parent class. The new class is called the derived or child class. Inheritance facilitates code reuse and supports the creation of a hierarchy of classes. There … Read more
In C++, classes and objects are fundamental concepts that support object-oriented programming (OOP). Here’s a brief overview of classes and objects in C++: Classes: In C++, a class is a user-defined data type that allows you to encapsulate data members and member functions into a single unit. Classes are the building blocks of object-oriented programming … Read more
