Top 5 Programming Languages In 2019


Programming languages are the set of instructions given to computer which are in human readable form. This languages use compiler to convert that instructions which are in human readable form to the computer understandable form. Due to programming languages, we can develop software, viruses, drivers etc.

Programming languages are very important to that person who are career in computer professional. Without programming language one cannot understand the working of computer and without knowing the languages computer professional is nothing.

There are so many programming languages which are must used by programmer to develop the new system, but some of the programming languages in 2019 are very popular and important to get the job as programmer, developers etc. So that Every programmer should know that programming languages.


Top 5 programming languages in 2019 which are very important for every programmer.


1. Java

Java is a programming language created by James Gosling from Sun Microsystems (Sun) in 1991. The target of Java is to write a program once and then run this program on multiple operating systems. The first publicly available version of Java (Java 1.0) was released in 1995. Sun Microsystems was acquired by the Oracle Corporation in 2010. Oracle has now the steermanship for Java. In 2006 Sun started to make Java available under the GNU General Public License (GPL). Oracle continues this project called OpenJDK.

For years, Java has been used to develop web-based applications. This functionality makes it a perfect candidate for blockchain technology. It is capable of operating in a network while at the same time maintain the independence of its architecture. Different devices in a blockchain network can remain autonomous even while accessing the network.


2. C#

There is slight decline in its demand this year. Being an object-oriented programming language from Microsoft was created to run on Microsoft’s .NET platform and to make rapid development. C# is greatly used in video game development, so if you wish to become a video game developer, you could learn it for your advantage.


3. Python

The history of Python programming language dates back to 1991 when it was created by Guidi van Rossum, a Dutch programmer. Today, Python is one of the most loved programming languages. Programmers love it because of its simplicity and also uses minimal resources. There is also a robust community of Python programmers. This makes it easy for one to access resources and even get the necessary help.

When it comes to blockchain programming, Python has proven itself to be highly reliable. Given that it is used for creating both standalone and web-based application, Python can easily fit in blockchain development.


4. C++

C++ is a super set of C. A little broader audience in terms of jobs. C++ is also used in embedded systems, games, graphics, web browsers, medical and engineering applications.

C and C++ have been used for scripting MySQL, one of the most widely used database management systems. C and C++ based software help form the backbone of various database-based enterprises, such as Google, Wikipedia, Yahoo and YouTube – to name a few.


5. JavaScript

Believe it or not but JavaScript is the #1 language of the web. The rise of frameworks like jQuery, Angular JS and React JS has made JavaScript even more popular. Since you just cannot stay away from the web, it's better to learn JavaScript sooner than later.

Even if you are not using Angular JS or React JS, there are many other libraries e.g. jQuery which are based on JavaScript and it's also the number one language for client-side validation, which makes it worth to learn JavaScript.


Simple Examples of Sum of Two Numbers of Each Languages

1. Java

import java.util.Scanner; class AddNumbers { public static void main(String args[]) { int x, y, z; System.out.println("Enter two integers to calculate their sum"); Scanner in = new Scanner(System.in); x = in.nextInt(); y = in.nextInt(); z = x + y; System.out.println("Sum of the integers = " + z); } }

2. C#

using System; public class funcexer3 { public static int Sum(int num1, int num2) { int total; total = num1 + num2; return total; } public static void Main() { Console.Write("\n\nFunction to calculate the sum of two numbers :\n"); Console.Write("---------------\n"); Console.Write("Enter a number: "); int n1= Convert.ToInt32(Console.ReadLine()); Console.Write("Enter another number: "); int n2= Convert.ToInt32(Console.ReadLine()); Console.WriteLine("\nThe sum of two numbers is : {0} \n", Sum(n1,n2) ); } }

3. Python

num1 = input('Enter first number: ') num2 = input('Enter second number: ') sum = float(num1) + float(num2) print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

4. C++

#include <iostream.h> #include <conio.h> void main() { int a, b, c; cout &lt;&lt; "Enter two integers to add\n"; cin &gt;&gt; a &gt;&gt; b; c = a + b; cout &lt;&lt;"Sum of the numbers: " &lt;&lt; c &lt;&lt; endl; getch(); }

5. JavaScript

<input type="text" placeholder="A" id="first"/> <input type="text" placeholder="B" id="second"/> <input type="text" placeholder="Sum of A & B" id="sum"/> <input type="submit" onClick="sum();"> <script> Function sum() { var A = document.getElementById("first").value; var B = document.getElementById("second").value; document.getElementById("sum").value = A+B; } </script>
