Back-2-Basics : Largest and Second Largest in an Array(C#)

It’s a basics code, just sharing it since since will be useful for some body, who is in needy.

I am just refresing my OOPS and Basic knowledge, just experimenting. Ha ha ha.

Advice to guyz, don’t simply copy it, try to understand the logic and do it by yourself.

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleAppPro
{
    /// <summary>
    /// 
    /// </summary>
    public class NumberOps
    {

        /// <summary>
        /// Runs the number ops.
        /// </summary>
        public void RunNumberOps()
        {
            Random rand = new Random();

            int[] input = new int[20];

            Console.WriteLine("Numbers to Process");
            Console.WriteLine("----------------------------");

            
            for (int i = 0; i < 20; i++)
            {
                input[i] = rand.Next(100); //Generating numbers in random (below 100)

               Console.Write(String.Format("{0},", input[i]));
            }

            Console.WriteLine("nnRESULTn----------------------------");
            FirstNSecondLargest(input);

            Console.Read();
        }

        /// <summary>
        /// Firsts the N second largest.
        /// </summary>
        /// <param name="inVals">The in vals.</param>
        public void FirstNSecondLargest(int[] inVals)
        {

            int largest = 0;
            int smallest = 0;
            int secondLargest = 0;
            int secondSmallest = 0;

            largest  =  inVals[0];
            secondLargest = 0;
            secondSmallest = 0;
            smallest = inVals[0];

            for (int iIndex = 0; iIndex < inVals.Length; iIndex++)
            {
                if (inVals[iIndex] > largest) //Largest Value
                {
                    secondLargest = largest;
                    largest = inVals[iIndex];
                }
                else if (inVals[iIndex] >= secondLargest && inVals[iIndex] != largest)
                {
                    secondLargest = inVals[iIndex]; //second largest
                }

                if (smallest >  inVals[iIndex]) //Smallest Value   
                {
                    
                    secondSmallest = smallest;
                    smallest = inVals[iIndex];
                }
                else if (inVals[iIndex] < secondSmallest && inVals[iIndex] != smallest)
                {
                    secondSmallest = inVals[iIndex]; //second smallest
                }
                
            }

            Console.WriteLine(String.Format("Largest: {0}, Second Largest: {1}, Second Smallest: {3}, Smallest: {2}", largest, secondLargest, smallest, secondSmallest));

            
        }
    }
}

PS: I have tested this only few times. If you find any issues in the logic. please notify me, so that i can fix it up for later use.

This is just an information sharing, hope this helps some body. Tweak it, if could and Happy Coding!!!
