    public Car(String brand, String model) {
        this.brand = brand;
        this.model = model;
    }

    public void startEngine() {
        System.out.println(brand + " " + model + " engine started.");
    }

    public static void main(String[] args) {
        Car myCar = new Car("Toyota", "Corolla");
        myCar.startEngine();  // Output: Toyota Corolla engine started.
    }
}

C++’s ability to provide close-to-hardware programming makes it indispensable for performance-critical applications. Here’s a simple C++ program demonstrating the use of classes and objects:

#include <iostream>
#include <string>

class Person {
private:
    std::string name;
    int age;

public:
    Person(std::string n, int a) : name(n), age(a) {}

    void introduce() {
        std::cout << "My name is " << name << " and I'm " << age << " years old." << std::endl;
    }
};

int main() {
    Person person("Alice", 30);
    person.introduce();  // Output: My name is Alice and I'm 30 years old.
    return 0;
}

5. Go: The Modern Systems Programming Language

Go, developed by Google, has gained significant traction in recent years and continues to be a top language in 2023, especially in the realm of cloud computing and microservices.

package main

import (
    "fmt"
    "time"
)

func sayHello(name string) {
    time.Sleep(time.Second)
    fmt.Printf("Hello, %s!\n", name)
}

func main() {
    go sayHello("Alice")
    go sayHello("Bob")
    time.Sleep(2 * time.Second)
}

6. TypeScript: The JavaScript Enhancer

TypeScript, a superset of JavaScript, has been gaining popularity and is considered one of the top programming languages in 2023, especially for large-scale JavaScript projects.

Key Features:

    name: string;
    age: number;
}

function greet(person: Person): string {
    return `Hello, ${person.name}! You are ${person.age} years old.`;
}

const john: Person = { name: "John", age: 30 };
console.log(greet(john));  // Output: Hello, John! You are 30 years old.

7. Rust: The Safe Systems Programming Language

Rust has been steadily climbing the ranks and is considered one of the most loved programming languages in 2023. It’s particularly valued for its focus on memory safety and concurrent programming.
