C#: Find maximum and minimum element in an array

C# Sharp Array: Exercise-9 with Solution

Write a C# Sharp program to find the maximum and minimum elements in an array.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise9
{
    public static void Main()
    {
        int[] arr1 = new int[100];  // Array to store elements
        int i, mx, mn, n;  // Variables for maximum, minimum, and size of array

        Console.Write("\n\nFind maximum and minimum element in an array :\n");
        Console.Write("--------------------------------------------------\n");

        Console.Write("Input the number of elements to be stored in the array :");
        n = Convert.ToInt32(Console.ReadLine());  // Read the number of elements

        Console.Write("Input {0} elements in the array :\n", n);
        for (i = 0; i < n; i++)
        {
            Console.Write("element - {0} : ", i);
            arr1[i] = Convert.ToInt32(Console.ReadLine());  // Read elements into the array
        }

        // Initializing maximum and minimum with the first element of the array
        mx = arr1[0];
        mn = arr1[0];

        // Finding maximum and minimum elements
        for (i = 1; i < n; i++)
        {
            if (arr1[i] > mx)  // If current element is greater than the current maximum
            {
                mx = arr1[i];  // Update maximum
            }

            if (arr1[i] < mn)  // If current element is smaller than the current minimum
            {
                mn = arr1[i];  // Update minimum
            }
        }

        // Display maximum and minimum elements
        Console.Write("Maximum element is : {0}\n", mx);
        Console.Write("Minimum element is : {0}\n\n", mn);
    }
}

Sample Output:

Find maximum and minimum element in an array :                                                                
--------------------------------------------------                                                            
Input the number of elements to be stored in the array :2                                                     
Input 2 elements in the array :                                                                               
element - 0 : 20                                                                                              
element - 1 : 25                                                                                              
Maximum element is : 25                                                                                       
Minimum element is : 20
