Largest Among Three Integers

Write a C# Sharp program to check the largest number among three given integers.

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(1, 2, 3));  // Output: 3
            Console.WriteLine(test(1, 3, 2));  // Output: 3
            Console.WriteLine(test(1, 1, 1));  // Output: 1
            Console.WriteLine(test(1, 2, 2));  // Output: 2
            Console.ReadLine();               // Keeping the console window open
        }

        // Method to find the maximum value among three integers
        public static int test(int x, int y, int z)
        {
            // Using Math.Max method to find the maximum value between x, y, and z
            // Math.Max is used twice to find the maximum value among the three integers
            var max = Math.Max(x, Math.Max(y, z));

            // Returning the maximum value among the three integers
            return max;
        }
    }
}

Sample Output:

3
3
1
2
