Common Programming Languages and Their Code


In the world of technology and computer science, programming languages are an essential component when it comes to creating and developing software and applications. These languages are highly specialized and are used to write instructions or code that tell a computer what to do. Each language has its own set of rules and syntax, making them unique in their own way. In this article, we will explore some of the most common programming languages used in computer programming and discuss their code and practical examples.

1) Java:
Java is a widely-used object-oriented programming language that is designed to be simple, secure, and platform-independent. Developed by James Gosling in the 1990s, Java has become the go-to language for building enterprise applications, web servers, mobile applications, and more. The code in Java is written in a specific style known as object-oriented programming (OOP) which helps in better organization and maintenance of code.


public class HelloWorld {

public static void main(String[] args) {

System.out.println(“Hello, World!”);



This simple code in Java is used to print the words “Hello, World!” on the screen. The “System.out.println” statement is used to display the output on the screen. This code is easy to understand and can serve as an excellent starting point for beginners in Java.

2) Python:
Python is a high-level, interpreted programming language that is widely used in various fields like web development, data analytics, artificial intelligence, and more. It is known for its simplicity and readability, making it a popular choice among programmers. The code in Python is written in a clear and concise syntax, making it easy for beginners to code and understand.


# Print Hello World

print(“Hello, World!”)

This simple code in Python is used to print the text “Hello, World!” on the screen. The “#” symbol is used to indicate a comment in Python. Comments are not executed and serve as notes for the programmer to understand the code better. This feature makes Python code highly readable and user-friendly.

3) C++:
C++ is a powerful object-oriented programming language that is widely used for developing high-performance applications and video games. It is an extension of the C language and provides features such as classes, objects, and templates, making it suitable for both low-level and high-level programming. The code in C++ is complex and requires a good understanding of programming concepts to write efficient and error-free code.


using namespace std;

int main()
// Print Hello World
cout << "Hello, World!" << endl; return 0; } This code in C++ uses the "cout" statement to print the words "Hello, World!" on the screen. The "<<" symbol is used to pass the text to be displayed. C++ code is highly efficient and is often used in projects where performance is crucial. 4) HTML: HTML (Hypertext Markup Language) is a core programming language used for creating and structuring web pages. Unlike the languages mentioned above, HTML is not a programming language but rather a markup language used to design the layout and content of a webpage. The code in HTML consists of tags, which are used to define different elements of a webpage. Example:

Hello World

Hello, World!

In this HTML code, the “” tag defines the beginning and end of the HTML document, the “” tag contains the title of the webpage, and the “” tag contains the content of the webpage. The “

” tag is used to define a heading, and the text inside it, “Hello, World!” will be displayed as the heading on the webpage.

In conclusion, programming languages are the backbone of software development, and each language serves a specific purpose. They require a logical and systematic approach to writing code and can be highly specialized depending on the project’s requirements. With the help of practical examples, we have explored some of the most common programming languages and their code, giving an overview of their features and uses. As technology continues to evolve, so do programming languages, and it is essential for programmers to stay updated with their knowledge and skills to keep up with the ever-changing demands of the digital world.
