What is Swift?

Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS, and Linux. It was created by Apple and is now an open source language. Swift is designed to work with Apple’s Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products.

Example:

func helloWorld() {
print(“Hello, world!”)
}

helloWorld() // prints “Hello, world!

What is Ruby?

Ruby is an open-source, object-oriented programming language. It was created in the mid-1990s by Yukihiro Matsumoto in Japan. Ruby is used for building web applications, websites, and other software.

Example:

# Create a new class called “Person”
class Person

# Define an initialize method to set the name
def initialize(name)
@name = name
end

# Define a method to greet the person
def greet
puts “Hello, my name is #{@name}!”
end
end

# Create a new person object
person = Person.new(“John”)

# Call the greet method
person.greet

What do you know about Swift programming language?

Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS, and beyond. It is designed to give developers the freedom and capabilities they need to create a variety of apps. Swift is easy to learn and use, and provides a safe and fast way to develop powerful apps.

An example of a program written in Swift is a simple calculator app. Here is a code snippet for a basic calculator:

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var resultLabel: UILabel!

var numberOnScreen:Double = 0

@IBAction func numbers(_ sender: UIButton) {

if let number = sender.currentTitle {

if number == “C” {

resultLabel.text = “0”

numberOnScreen = 0

} else {

if resultLabel.text == “0” {

resultLabel.text = number

} else {

resultLabel.text = resultLabel.text! + number

}

numberOnScreen = Double(resultLabel.text!)!

}

}

}

}

This code snippet creates a basic calculator app that allows the user to input numbers and perform basic calculations.

What programming language is used to program an Arduino board?

The Arduino boards are programmed using a variant of the C/C++ programming language.

Example:

// Blink an LED

int ledPin = 13; // LED connected to digital pin 13

void setup() {
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}

void loop() {
digitalWrite(ledPin, HIGH); // sets the LED on
delay(1000); // waits for a second
digitalWrite(ledPin, LOW); // sets the LED off
delay(1000); // waits for a second
}
