It is collection of character or char type array.

In C, an array is a collection of elements of the same data type, stored in contiguous memory locations. An index is used to access the elements of an array.

Decision-making statements Contains Conditional,unconditional and repetitive statements

In C, format specifiers are used to specify the type of data being read or displayed when using functions like printf and scanf. These are a few frequently used C format specifiers:

Basic fundamental tools is combination of Character sets, Keywords, data type, constants, variables.

C is a general-purpose, procedural programming language created by Dennis Ritchie at Bell Labs in the early 1970s. It was designed to be a system programming language and eventually became widely used due to its power, flexibility, and efficiency. Here are some key aspects and features of the C programming language:

In HTML and CSS, an ID (identifier) is a unique attribute used to identify an individual element on a webpage. Each ID must be unique within the document, distinguishing one element from all others.

The anchor (<a>) and image (<img>) tags are two fundamental HTML elements used to create links and embed images in web pages.

Here we discuss paragraph tag , acronym tags, and marquee tags.

HTML (Hypertext Markup Language) is defined as the standard markup language for creating and structuring web pages. It forms the backbone of the World Wide Web and is essential for creating and rendering web content in web browsers. HTML is not a programming language; rather, it is a markup language used to define the structure and content of web documents.

Templates in C++ allow you to construct generic code that can deal with multiple data types without having to replicate the code for each one. In C++, templates are fundamental for constructing flexible and reusable classes and functions. In C++, there are two types of templates: function templates and class templates.

Because there are no library functions with predetermined definitions, a user-defined function is one that is written by the user when writing any application. To fulfill the user's individual needs, the user must create his or her own functions. Such functions must be appropriately defined by the user. There is no such necessity to include any specific library in the program.

Inheritance is a fundamental concept in object-oriented programming, and it allows you to create new classes (derived or subclass) that inherit properties and behaviors from existing classes (base or superclass). In C++, inheritance is a key feature, and it enables you to establish a hierarchy of classes.

In C++, classes are the building blocks of object-oriented programming (OOP). They serve as blueprints or templates for creating objects. Classes define the structure and behavior of objects, encapsulating data (attributes) and functions (methods) that operate on that data.

In C, input and output functions are used to interact with the user and the external world. These functions allow you to read data from the user or files and write data to the screen or files. The standard library provides several functions for input and output

In the C programming language, operators are special symbols or keywords that perform operations on operands. Operands are the values or variables that operators act upon

In C++, input and output operations are commonly performed using the Standard Input/Output Library, which includes the <iostream> header. This library provides the 'cin' and 'cout' objects for reading input and displaying output, respectively.

To find the biggest number in a 1D array in C, you can iterate through the array and keep track of the maximum value encountered.

To check if a character is a vowel or a consonant in C, you can write a simple program that evaluates whether the character is one of the vowels (a, e, i, o, u) or not. Here's a basic example of how to do this:

C++ is a powerful, high-level programming language that is widely used for developing a wide range of applications, from system software to video games and web applications. It was developed as an extension of the C programming language and introduced several features that make it a versatile and efficient language for software development.

Collection of Char or char type array.

LINQ (Language Integrated Query) is a feature in C# that allows us to perform queries against data sources, which can be arrays, collections, or any type of databases, using a SQL-like syntax. In this article, we will cover some basic concepts and functionalitites of LINQ and learn how to use it in your C# application

Threading is an important aspect of programming that allows developers to perform multiple tasks at the same time. In C#, threading is an efficient way to run multiple pieces of code concurrently.

They are identify after method name and in the bracket.The information can be given to method as a parameter

Method is a series of statements that together perform a task.

It is a way to represent memory location through symbol so that it can be easily identified.

To pass a reference of arguments to the function the ref keyword is used in C#.

The break statement is used to terminate the loop or statement in which it present. This statement is used to skip over the execution part of the loop on a certain condition.

Constructor is a special method which is invoked automatically at the time of object creation.

Abstraction is used to hide some information and show essential information to user.

C# List<T> class is used to store and fetch elements. It can also have duplicate elements. It is found in System.Collections.Generic namespace. List<T> class in C# represents a strongly typed list of objects. List<T> provides functionality to create a list of objects, find list items, sort list, search list, and manipulate list items. In List<T>, T is the type of object. What is the ‘T’ in List<T>? List<T> class represents a strongly typed list of objects. List<T> provides functionality to create a list of objects, find list items, sort list, search list, and manipulate list items. In List<T>, T is the type of objects. How to create List in C#? List is a generic class and is defined in the System.Collections.Generic namespace. You must import this namespace in your project to access the List<T> class. using System.Collections.Generic; The List<T> is a generic collection, so you need to specify a type parameter for the type of data it can store. The following example shows how to create a list and add elements.

In C# if-else statement also tests the condition. It executes the if block if the condition is true otherwise else block, is executed. the else statement to specify a block of code to be executed if the condition is False. the if-else statement checks a Boolean expression and executes the code based on if the expression is true or false. The if part of the code executes when the value of the expression is true. The else part of the code is executed when the value of the expression is false.

If statement will execute a block of code if the given condition is true. The if statement checks a Boolean expression and executes the code based on if the expression is true

The do while loop statement executes a statement or a block of statements while a specified Boolean expression evaluates to true. Because that expression is evaluated after each execution of the loop, a do-while loop executes one or more times.The do while loop stops execution exits when a boolean condition evaluates to false. Because the while(condition) specified at the end of the block, it certainly executes the code block at least once.This differs from the while loop, which executes zero or more times. The do while loop is the same as while loop except that it executes the code block at least once

C# provides the while loop to repeatedly execute a block of code as long as the specified condition returns false. The while loop starts with the while keyword, and it must include a boolean conditional expression inside brackets that returns either true or false. It executes the code block until the specified conditional expression returns false. The condition is given in the beginning of the loop and all statements are executed till the given boolean condition satisfies when the condition becomes false, the control will be out from the while loop else It executes the code block until the specified conditional expression returns false.

A two-dimensional (2D) array is an arrangement of items in C that are arranged in a grid and are individually identified by a pair of indices: a row index and a column index. A 2D array can be compared to a table or matrix that has rows and columns. A 2D array in C is declared, initialised, and used as follows:

A control structure in C called a switch statement is used to make decisions based on the value of a variable or expression. It enables you to run a block of code connected to the first matching case after testing a variable against a set of values (cases). The switch statement's fundamental grammar is as follows:

A do-while loop is a sort of loop construct in C that repeatedly runs a block of code as long as a stated condition is true. The do-while loop, as opposed to the while loop, ensures that the code block is performed at least once, even if the condition is initially false. The basic syntax of a do-while loop in C is as follows:

A parameterized constructor in Java is a constructor that accepts one or more parameters when creating a class object. These parameters are used to set the values of the object's instance variables.

A default constructor in Java is one that is provided by the Java compiler if no other constructors are explicitly defined in a class. The default constructor takes no arguments and is in charge of setting the object's fields to default values.

By defining your own classes, you can produce user-defined data types in Java. These classes let you create unique data structures that encapsulate data and action. Here is how to make a Java user-defined data type:

Type conversions between classes in an inheritance hierarchy are referred to as "upcasting" and "downcasting" in Java. When working with polymorphism and inheritance, these conversions are frequently required. Let's look at both ideas:

In the static method, there is no need for objects. but In non-static method there is requirement of Object.

you can import any package by this way; here I show you how to import java.util.list package

A NumberFormatException is produced in Java when you try to convert a string to a numeric type (such as int, double, float, etc.) but the string's format is incompatible with the required format for that numeric type. This is common when using parsing techniques such as Integer.parseInt(), Double.parseDouble(), or Float.parseFloat().

An ArrayIndexOutOfBoundsException is a runtime exception in Java that happens when you attempt to access an array element with an index that is outside the array's valid range of indices. In other words, you're attempting to access an element in the array at an index that doesn't exist.

In Java, access modifiers are keywords that control the visibility and accessibility of classes, fields, methods, and other members within a class or package.

An array is a sort of data structure in Java that allows you to store numerous values of the same type. It allows you to easily organise and manipulate data collections.

In Java, the LinkedList class implements the List interface and provides a doubly-linked list data structure. It provides a versatile means of storing and manipulating a collection of items. A LinkedList, unlike an ArrayList, uses references to connect components rather than contiguous memory allocation.

When you need to manage strings efficiently in Java, you should utilise the StringBuilder class. Unlike the immutable String class, the StringBuilder class allows you to change the contents of a string without creating a new object each time.

The List class has a lot of useful methods that you can use to organize data. This article will cover how to sort the items in your list and make them easier to read. The Sort method is the simplest way to sort a C# list

To generate an image using C#, you can utilize the System.Drawing namespace, which provides classes for working with images. Here's a simple example that demonstrates how to create a new image and save it to a file:

First C# Program

Hello guys, sometime we need to shuffle our list or array randomly without being in a certain order. So , in this article we will learn how to shuffle a list randomly in c#.

Shuffling an array means we want to randomly rearranging the list or an array.
