Chapter 1: Introduction to Programming Languages

In this article, we will examine the leading programming languages by utilizing a straightforward "hello user" application. As someone engaged in programming, I recognize how overwhelming it can be to select the appropriate language for your project. With numerous options available, each possessing unique advantages and drawbacks, it’s essential to navigate this landscape thoughtfully.

To facilitate this, I will break down the top 10 programming languages and present a side-by-side comparison using a basic "hello user" application. This approach will provide you with a clearer perspective on each language's features and assist you in making a well-informed choice for your next venture. Let's dive in!

Chapter 2: Programming Language Implementations

In this section, we will provide examples of the "hello user" application across various programming languages, showcasing their unique syntax and capabilities.

Java Implementation:

import java.util.Scanner;

public class HelloUser {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("Please enter your name:");

String userName = input.nextLine();

if (userName.equals("Tom")) {

System.out.println("Hello Tom, nice to see you again!");

} else {

System.out.println("Hello " + userName);

}

}

}

Python Implementation:

user_name = input("Please enter your name: ")

if user_name == "Tom":

print("Hello Tom, nice to see you again!")

else:

print("Hello " + user_name)

C++ Implementation:

#include <iostream>

#include <string>

int main() {

std::string user_name;

std::cout << "Please enter your name: ";

std::cin >> user_name;

if (user_name == "Tom") {

std::cout << "Hello Tom, nice to see you again!" << std::endl;

} else {

std::cout << "Hello " << user_name << std::endl;

}

return 0;

}

C# Implementation:

using System;

class HelloUser {

static void Main(string[] args) {

Console.WriteLine("Please enter your name:");

string userName = Console.ReadLine();

if (userName == "Tom") {

Console.WriteLine("Hello Tom, nice to see you again!");

} else {

Console.WriteLine("Hello " + userName);

}

}

}

JavaScript Implementation:

var userName = prompt("Please enter your name:");

if (userName === "Tom") {

console.log("Hello Tom, nice to see you again!");

} else {

console.log("Hello " + userName);

}

Swift Implementation:

import Foundation

print("Please enter your name:")

let userName = readLine()

if userName == "Tom" {

print("Hello Tom, nice to see you again!")

} else {

print("Hello (userName!)")

}

PHP Implementation:

<?php

echo "Please enter your name: ";

$user_name = trim(fgets(STDIN));

if ($user_name == "Tom") {

echo "Hello Tom, nice to see you again!n";

} else {

echo "Hello " . $user_name . "n";

}

?>

Ruby Implementation:

puts "Please enter your name:"

user_name = gets.chomp

if user_name == "Tom"

puts "Hello Tom, nice to see you again!"

else

puts "Hello #{user_name}"

end

Go Implementation:

package main

import "fmt"

func main() {

fmt.Print("Please enter your name: ")

var userName string

fmt.Scan(&userName)

if userName == "Tom" {

fmt.Println("Hello Tom, nice to see you again!")

} else {

fmt.Println("Hello", userName)

}

}

Kotlin Implementation:

fun main() {

println("Please enter your name:")

val userName = readLine()

if (userName == "Tom") {

println("Hello Tom, nice to see you again!")

} else {

println("Hello $userName")

}

}

In conclusion, this article has showcased a simple "hello user" application implemented in the top 10 programming languages, including Java, Python, C++, C#, JavaScript, Swift, PHP, Ruby, Go, and Kotlin. Each example highlights the fundamental use of input and decision-making in each language, facilitating an easy comparison of their capabilities.
