C# Exercise: 70 Conditional and boolean

In this C# exercise, you are asked to write a program that uses the conditional operator (also known as the ternary operator) to assign a boolean variable named "bothEven" the value "true" if the two numbers entered by the user are even, or "false" if either of them is odd.

The conditional operator in C# has the following syntax: condition ? value_if_true : value_if_false. In this case, the condition to be evaluated is whether both numbers are even. To check if a number is even, the modulo operator (%) can be used, which returns the remainder of dividing two numbers. If the remainder of dividing by 2 is zero, the number is even.

This exercise is useful for practicing the use of the ternary operator instead of longer conditional structures. It will also help you become familiar with how to perform parity checks and how to assign boolean values based on evaluated conditions. It is a great exercise to understand the syntax and logic of conditional operators in C#.

Write a C# program that uses the conditional operator to give a boolean variable named "bothEven" the value "true" if two numbers entered by the user are the even, or "false" if any of them is odd.

 Example Code

using System;  // Import the System namespace for basic functionality

class Program  // Define the main class
{
    static void Main()  // The entry point of the program
    {
        // Ask the user to enter two numbers
        Console.Write("Enter the first number: ");
        int num1 = int.Parse(Console.ReadLine());  // Read and convert the first input to an integer

        Console.Write("Enter the second number: ");
        int num2 = int.Parse(Console.ReadLine());  // Read and convert the second input to an integer

        // Use the conditional operator to check if both numbers are even
        bool bothEven = (num1 % 2 == 0 && num2 % 2 == 0) ? true : false;

        // Display the result
        Console.WriteLine($"Both numbers are even: {bothEven}");
    }
}
