int main() {
printf("Hello, Hunter!\n");
return 0;
}What it is: A powerful extension of C with objects, templates, and many abstractions.
Best for: Game engines, high-performance apps, real-time systems, graphics, large codebases.
Key features: High performance, OOP + generic programming, powerful but complex.

using namespace std;
int main() {
cout << "Hello, Hunter!" << endl;
return 0;
}What it is: A modern, object-oriented language developed by Microsoft, runs on .NET.
Best for: Windows apps, Unity games, web apps (ASP.NET), enterprise systems.
Key features: Strong typing, LINQ, async/await, great tooling in Visual Studio.
// C# example
using System;
class Program {
static void Main() {
Console.WriteLine("Hello, Hunter!");
}
}What it is: A dynamic, expressive language famous for Ruby on Rails.
Best for: Web apps, scripting, rapid development, clean code lovers.
Key features: Very readable, “developer happiness” focused, strong web framework ecosystem.
# Ruby example
def greet(name)
puts "Hello, #{name}!"
end
greet("Hunter")What it is: A server-side scripting language heavily used in web development.
Best for: Dynamic websites, WordPress, legacy systems, simple backends.

?>What it is: A statically typed, compiled language from Google.
Best for: Fast APIs, microservices, CLI tools, cloud services.
Key features: Simple syntax, built-in concurrency (goroutines), fast compilation.
// Go example
package main
import "fmt"
func main() {
fmt.Println("Hello, Hunter!")
}What it is: A systems language focused on safety and performance without garbage collection.
Best for: Systems programming, performance-critical services, game engines, CLI tools.
Key features: Memory safety, strong type system, no data races, modern tooling.
// Rust example
fn main() {
println!("Hello, Hunter!");
}What it is: Apple’s modern language for iOS, macOS, watchOS, and tvOS apps.
Best for: iPhone/iPad apps, Mac apps, Apple ecosystem development.
Key features: Safe by design, modern syntax, good performance, strong Apple tooling.
// Swift example
import Foundation
let name = "Hunter"
print("Hello, \(name)!")What it is: A modern JVM language that is fully interoperable with Java.
Best for: Android apps, backend services, replacing or combining with Java.
Key features: Null safety, concise syntax, coroutines, great Android support.
// Kotlin example
fun main() {
val name = "Hunter"
println("Hello, $name!")
}What it is: A superset of JavaScript that adds static typing.
Best for: Large JS codebases, web apps, libraries, safer front-end and back-end JS.
Key features: Types, better tooling, compiles to plain JavaScript.
// TypeScript example
function greet(name: string): void {
console.log(`Hello, ${name}!`);
}
greet("Hunter");What it is: A markup language that defines the structure of web pages.
Best for: Creating page content, text, images, links, base layout.
Key features: Not a programming language, but the foundation of the web.
<!-- HTML example -->
<h1>Hello, Hunter!</h1>
<p>Welcome to my site.</p>What it is: A language for managing and querying relational databases.
Best for: Storing and retrieving structured data.
Key features: Declarative style, used with MySQL, PostgreSQL, SQLite, etc.
-- SQL example
SELECT * FROM users
WHERE name = 'Hunter';What it is: A command-line shell and scripting language for Unix-like systems.
Best for: Automation, server scripts, quick tasks, DevOps.
