ما الإدخال والإخراج؟

عرض الإخراج

using System;

class Program {
    static void Main() {
        Console.WriteLine("Hello, World!"); 
// Outputs: Hello, World!
    }
}

استقبال الإدخال من المستخدم

using System;

class Program {
    static void Main() {
        Console.WriteLine("What is your name?");
        string name = Console.ReadLine(); 
// Reads input from the user
        Console.WriteLine("Hello, " + name + "!"); 
// Outputs a greeting
    }
}

تحويل الإدخال

using System;

class Program {
    static void Main() {
        Console.WriteLine("Enter your age:");
        int age = int.Parse(Console.ReadLine()); // Converts input to an integer
        Console.WriteLine("You are " + age + " years old.");
    }
}

التعامل مع الإدخال الرقمي

using System;

class Program {
    static void Main() {
        try {
            Console.WriteLine("Enter a number:");
            double number = double.Parse(Console.ReadLine());
            Console.WriteLine("You entered: " + number);
        } catch (FormatException) {
            Console.WriteLine("Invalid input. Please enter a valid number.");
        }
    }
}

دمج الإدخال والإخراج

using System;

class Program {
    static void Main() {
        Console.WriteLine("What is your name?");
        string name = Console.ReadLine();

        Console.WriteLine("How old are you?");
        int age = int.Parse(Console.ReadLine());

        Console.WriteLine("Hello, " + name + ". You are " + age + " years old.");
    }
}

تحدي تدريبي

using System;

class Program {
    static void Main() {
        Console.WriteLine("What is your favorite color?");
        string color = Console.ReadLine();

        Console.WriteLine("What is your favorite number?");
        int number = int.Parse(Console.ReadLine());

        Console.WriteLine("Your favorite color is " + color + " and your favorite number is " + number + ".");
    }
}
