Greetings, fellow programming enthusiasts! If you are new to the wonderful world of Pascal and wondering how to say “Hello, World!” in this language, you’ve come to the right place. In this guide, we’ll explore both formal and informal ways to greet the world, along with some useful tips and examples. So, let’s dive in!

Formal Greetings
When it comes to formal greetings, Pascal provides a simple yet elegant syntax. We use the built-in writeln function, which allows us to display text on the console output. Here’s how you can say “Hello, World!” formally in Pascal:
program HelloWorld;
begin
writeln(‘Hello, World!’);
end.
The above code snippet defines a Pascal program called “HelloWorld” and uses the writeln function to output the message “Hello, World!” to the console.
Informal Greetings
If you prefer a more casual approach to programming, Pascal allows you to interact with the user through input/output messages. Let’s see how we can create an informal “Hello, World!” program:
program HelloWorld;
var
name: string;
begin
writeln(‘What is your name?’);
readln(name);
writeln(‘Hello, ‘ + name + ‘!’);
end.
In this informal version, we introduce a string variable called “name” to store the user’s input. After displaying the message “What is your name?” using writeln, we use the readln function to read the user’s input and store it in the “name” variable. Finally, we greet the user by concatenating their name with the string “Hello, ” and display it using writeln.
Tips and Examples
1. Using Escape Characters
Pascal supports various escape characters that allow you to include special characters within your greetings. For example, if you want to add quotation marks within your message, you can use the escape character \. Here’s an example:
writeln(‘She said, \”Hello, World!\”‘);
2. Incorporating Variables
As shown in the informal example, you can include variables in your greetings. This adds personalization and interactivity to your program. Experiment with different variables and prompts to create engaging dialogues with your users.
3. Formatting Output
Pascal provides various ways to format your output. You can utilize newlines (\n) and tabs (\t) to structure your greetings. Here’s an example:
writeln(‘Hello, ‘ + name + ‘\nNice to meet you!\tWelcome to Pascal programming!’);
4. Language Adaptation
If you’re using Pascal in a non-English-speaking region, you might want to adapt the greeting to your local language. Simply modify the output message within the writeln function to cater to your regional audience.
Conclusion
Congratulations on learning how to say “Hello, World!” in Pascal! In this guide, we explored both formal and informal greetings, along with some tips and examples to make your programs more engaging and interactive. Remember to have fun while coding and keep exploring the exciting possibilities of Pascal programming!
