C Language Introduction

C may be a procedural artificial language. it absolutely was at the start developed by Dennis Ritchie between 1969 and 1973. it absolutely was in the main developed as a system artificial language to jot down OS. the most options of C language embody low-level access to memory, straightforward set of keywords, and clean vogue, these options create C language appropriate for system programming like OS or compiler development.
Many later languages have borrowed syntax/features directly or indirectly from C language. Like syntax of Java, PHP, JavaScript and lots of alternative languages is principally supported C language. C++ is sort of a superset of C language (There area unit few programs that will compile in C, however not in C++).

Beginning with C programming:

Structure of a C program
After the on top of discussion, we are able to formally assess the structure of a C program. By structure, it's meant that any program will be written during this structure solely. Writing a C program in the other structure can therefore result in a Compilation Error.



Header Files Inclusion: the primary and foremost element is that the inclusion of the Header files in an exceedingly C program.
A header file may be a file with extension .h that contains C operate declarations and macro definitions to be shared between many supply files.



Some of C Header files

stddef.h – Defines several useful types and macros.
stdint.h – Defines exact width integer types.
stdio.h – Defines core input and output functions
stdlib.h – Defines numeric conversion functions, pseudo-random network generator, memory allocation
string.h – Defines string handling functions
math.h – Defines common mathematical functions
Syntax to include a header file in C:

#include <(header_file_name).h>
Main Method Declaration: The next part of a C program is to declare the main() function. The syntax to declare the main function is:
Syntax to Declare main method:

int main()
{}

Variable Declaration: subsequent a part of any program is that the variable declaration. It refers to the variables that area unit to be utilized in the operate. Please note that in program, no variable may be used while not being declared. conjointly in an exceedingly program, the variables area unit to be declared before any operation within the operate.
Example:

int main()
{
    int a;
.
.

Body: Body of a operate in program, refers to the operations that area unit performed within the functions. It is something like manipulations, searching, sorting, printing, etc.
Example:


int main()
{
    int a;

    printf("%d", a);
.
.

Return Statement: The last half in any programme is that the come statement. The come statement refers to the returning of the values from a operate. This come statement and come worth depend on the return-type of the operate. as an example, if the come kind is void, then there'll be no come statement. In the other case, there'll be a come statement and therefore the come worth are of the sort of the required return-type.
Example:

int main()
{
    int a;

    printf("%d", a);

    return 0;
}



#include <stdio.h>
int main(void)
{
printf("GeeksQuiz");
return 0;
}

Let us analyze the command by line.
Line 1: [ #include ] during a C program, all lines that begin with # square measure processed by preprocessor that may be a program invoked by the compiler. during a} very basic term, preprocessor takes a C program and produces another C program. The created program has no lines beginning with #, all such lines square measure processed by the preprocessor. within the on top of example, preprocessor copies the preprocessed code of stdio.h to our file. The .h files square measure referred to as header files in C. These header files typically contain declaration of functions. we'd like stdio.h for the operate printf() employed in the program.





Line two [ int main(void) ] There should to be start line from wherever execution of compiled C program begins. In C, the execution usually begins with initial line of main(). The void written in brackets indicates that the most doesn’t take any parameter (See this for additional details). main() are often written to require parameters conjointly. we'll be covering that in future posts.
The int written before main indicates come back style of main(). the worth came by main indicates standing of program termination. See this post for additional details on come back sort.

Line three and 6: [ ] In C language, a try of frizzy brackets outline a scope and primarily employed in functions and management statements like if, else, loops. All functions should begin and finish with frizzy brackets.

Line four [ printf(“Sayed”); ] printf() may be a commonplace library operate to print one thing on commonplace output. The punctuation mark at the top of printf indicates line termination. In C, punctuation mark is often wont to indicate finish of statement.

Line five [ come back 0; ] The come back statement returns the worth from main(). The came worth could also be utilized by package to grasp termination standing of your program. the worth zero usually suggests that no-hit termination.

Linux: For UNIX operating system, gcc comes bundled with the UNIX operating system, Code Blocks may also be used with UNIX operating system.

Introduction to Object Oriented Programming in JavaScript

Introduction to Object bound Programming in JavaScript
As JavaScript is wide employed in net Development, during this article we might explore a number of the article bound mechanism supported by JavaScript to urge most out of it. a number of the common interview question in JavaScript on OOPS includes,- “How Object-Oriented Programming is enforced in JavaScript? however they dissent from alternative languages? are you able to implement Inheritance in JavaScript then on…”

There square measure bound options or mechanisms that makes a Language Object bound like:

• Object
• Classes
• Encapsulation
• Inheritance

Let’s dive into the small print of every one in all them and see however they're enforced in JavaScript.

Object– associate Object could be a distinctive entity that contains property and ways. as an example “car” could be a world Object, that have some characteristics like color, type, model, HP and performs bound action like drive. The characteristics of associate Object square measure known as as Property, in Object bound Programming and therefore the actions square measure known as ways. associate Object is associate instance of a category. Objects square measure all over in JavaScript virtually each component is associate Object whether or not it's a perform,arrays and string.
Note: a way in javascript could be a property of associate object whose worth could be a perform.
Object will be created in 2 ways that in



    Using an Object Literal
//Defining object
let person = {
first_name:’SI’,
last_name: ‘Sayed’,

//method
getFunction : function(){
return (`The name of the person is
${person.first_name} ${person.last_name}`)
},
//object within object
phone_number : {
mobile:’12345′,
landline:’6789′
}
}

console.log(person.getFunction());
console.log(person.phone_number.landline);


Using Object.create() method: the thing.create() methodology creates a brand new object, exploitation associate degree existing object because the model of the new created object.
// Object.create() example a


// Defining class using es6
class Vehicle {
constructor(name, maker, engine) {
this.name = name;
this.maker = maker;
this.engine = engine;
}
getDetails(){
return (`The name of the bike is ${this.name}.`)
}
}
// Making object with the help of the constructor
let bike1 = new Vehicle(‘Hayabusa’, ‘Suzuki’, ‘1340cc’);
let bike2 = new Vehicle(‘Ninja’, ‘Kawasaki’, ‘998cc’);
console.log(bike1.name); // Hayabusa
console.log(bike2.maker); // Kawasaki
console.log(bike1.getDetails());


// Defining class in a Traditional Way.
function Vehicle(name,maker,engine){
this.name = name,
this.maker = maker,
this.engine = engine
};

Vehicle.prototype.getDetails = function(){
console.log('The name of the bike is '+ this.name);
}

let bike1 = new Vehicle('Hayabusa','Suzuki','1340cc');
let bike2 = new Vehicle('Ninja','Kawasaki','998cc');

console.log(bike1.name);
console.log(bike2.maker);
console.log(bike1.getDetails());

Encapsulation – the method of wrapping property and performance inside one unit is understood as encapsulation.
Let’s perceive encapsulation with associate degree example.
//encapsulation example



class person{
constructor(name,id){
this.name = name;
this.id = id;
}
add_Address(add){
this.add = add;
}
getDetails(){
console.log(`Name is ${this.name},Address is: ${this.add}`);
}
}
let person1 = new person(‘Mukul’,21);
person1.add_Address(‘Delhi’);
person1.getDetails();


In the higher than example we tend to merely produce associate person Object victimisation the creator and Initialize it property and use it functions we tend to aren't hassle regarding the implementation details. we tend to square measure operating with associate Objects interface while not considering the implementation details.
Sometimes encapsulation refers to concealing knowledge|of knowledge|of information} or data Abstraction which implies representing essential options concealing the background detail. Most of the OOP languages offer access modifiers to limit the scope of a variable, however their aren't any such access modifiers in JavaScript however their square measure bound method by that we will limit the scope of variable inside the Class/Object.



Example:

// Abstraction example
function person(fname,lname){
let firstname = fname;
let lastname = lname;
let getDetails_noaccess = function(){
return (`First name is: ${firstname} Last
name is: ${lastname}`);
}

this.getDetails_access = function(){
return (`First name is: ${firstname}, Last
name is: ${lastname}`);
}
}
let person1 = new person(‘Mukul’,’Latiyan’);
console.log(person1.firstname);
console.log(person1.getDetails_noaccess);
console.log(person1.getDetails_access());


In the on top of example we have a tendency to try and access some property(person1.firstname) and functions(person1.getDetails_noaccess) however it returns undefine whereas their may be a methodology that we are able to access from the person object(person1.getDetails_access()), by dynamic the thanks to outline a perform we are able to limit it


Inheritance – it's an inspiration within which some property associated strategies of an Object is being employed by another Object. in contrast to most of the OOP languages wherever categories inherit categories, JavaScript Object inherits Object i.e. bound options (property and methods)of one object will be reused by different Objects.
Lets’s perceive inheritance with example:



//Inhertiance example
class person{
constructor(name){
this.name = name;
}
//method to return the string
toString(){
return (`Name of person: ${this.name}`);
}
}
class student extends person{
constructor(name,id){
//super keyword to for calling above class constructor
super(name);
this.id = id;
}
toString(){
return (`${super.toString()},Student ID: ${this.id}`);
}
}
let student1 = new student(‘Mukul’,22);
console.log(student1.toString())


In the higher than example we have a tendency to outline AN Person Object with bound property and technique and so we have a tendency to inherit the Person Object within the Student Object and use all the property and technique of person Object furthermore outline bound property and ways for Student.
Note: The Person and Student object each have same technique i.e toString(), this can be referred to as as technique dominant. technique dominant permits technique in a very kid category to possess a similar name and technique signature as that of a parent category.
In the higher than code, super keyword is employed to refer immediate parent category instance variable.

JavaScript :

The awing Script

Either you like it or hate it, however within the age of Microservice and REST API, you'll be able to not ignore JavaScript.
JavaScript was once upon a time used solely in consumer side(browser), however node js (execution engine/run time/web server) have created doable to run javascript on server aspect. JavaScript is all over – on Desktop/Server/Mobile.You can produce mobile internet app with javascript and html5, that has ton of benefits like save licensing price $99 yearly to pay Apple for creating IOS apps and you don’t have to be compelled to purchase macintosh portable computer to form your IOS app(Apple’s app will solely be created in MAC).

.JS

JavaScript has stormed the net technology and these days tiny package ventures to fortune five hundred, all ar victimization node js for internet apps. Recently wordpress.com has rewritten its dashboard in javascript, paypal additionally selected to rewrite a number of its parts in javascript. Be it google/twitter/facebook, javascript is vital for everybody. it's employed in applications like single page applications, Geolocation genus Apis, internet advertisements etc.
However JavaScript is quirky/dynamic/scripting/ purposeful destined language, and it's its own idiosyncrasies. it's not climbable, it's smart for a few 3000 line of code except for a much bigger app, it becomes troublesome to manage ,read and rectify. additionally not everyone seems to be greatly acquainted to JavaScript.

You might generally suppose that, I don't understand abundant of a JavaScript then “How to be JavaScript Developer while not abundant data of JavaScript?”

To ease down our work, some sensible developers/companies have created compiler/transpiler that convert your alternative language code into javascript code.(Best of each worlds)





Java: Java could be a darling of open supply, backed by Oracle/IBM/Google/Red hat. most variety of developers within the world ar Java developers(around ten millions). most variety of comes in github and apache ar supported Java.

GWT could be a development toolkit for building and optimizing advanced browser-based application.
Its goal is to alter productive development of superior internet applications while not the developer having to be Associate in Nursing skilled in browser quirks, XMLHttpRequest, and JavaScript. It’s open supply, fully free, and utilized by thousands of developers round the world.
JSweet: A transpiler from Java to TypeScript/JavaScript It contains 1000+ well-typed JavaScript libraries offered from Java.
Kotlin :-Kotlin could be a statically-typed programing language that runs on the Java Virtual Machine and can also be compiled to JavaScript ASCII text file. in contrast to most programming languages, Kotlin language isn't created by domain or work however it's created by an expert company jetbrains.
Scala: mixture of object destined and purposeful approach. it's a static language, however is use as a dynamic language. several massive enterprises like LinkedIn, Twitter ar written in Scala. Again, you write code in scala and scala-js involves rescue and code gets 

What is HTML?
