Largest in Range 20-30

Write a C# Sharp program to find the largest value from two positive integer values in the range 20..30 inclusive. Return 0 if neither is in that range.

Sample Solution:-

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Displaying the output of the 'test' method with different integer values
            Console.WriteLine(test(78, 95));   // Output: 95
            Console.WriteLine(test(20, 30));   // Output: 30
            Console.WriteLine(test(21, 25));   // Output: 25
            Console.WriteLine(test(28, 28));   // Output: 28
            Console.ReadLine();                // Keeping the console window open
        }

        // Method to compare two integers and return the larger one based on certain conditions
        public static int test(int x, int y)
        {
            // Check if both x and y are within the range [20, 30]
            if (x >= 20 && x <= 30 && y >= 20 && y <= 30)
            {
                // If x is greater than or equal to y, return x
                if (x >= y)
                {
                    return x;
                }
                else // If y is greater than x, return y
                {
                    return y;
                }
            }
            else if (x >= 20 && y <= 30) // If x is within the range [20, 30], return x
            {
                return x;
            }
            else if (y >= 20 && y <= 30) // If y is within the range [20, 30], return y
            {
                return y;
            }
            else // If neither x nor y is within the range [20, 30], return 0
            {
                return 0;
            }
        }
    }
}

Sample Output:

0
30
25
28

• Write a C# program to find the smallest value from two integers in the range 20–30. Return 0 if neither is in the range.
• Write a C# program to return the larger of two integers only if both are in the range 20–30 and their sum is divisible by 5.
• Write a C# program that returns the number closest to the midpoint of 20–30 from two integers, or 0 if neither is in the range.
• Write a C# program to return the larger integer in the 20–30 range only if it's not equal to the smaller one.
