this is perfectly work for any number-- if number is single digit or more then one digit number ==> static void Main(string[] args) { Console.WriteLine("Enter number: "); int num = Convert.ToInt32(Console.ReadLine()); int FirstHigest = 0, SecondHigest = 0, temp = 0; if (num >= 10) { while (num > 0) { temp = num % 10; num = num / 10; if (temp > FirstHigest) { SecondHigest = FirstHigest; FirstHigest = temp; } else if (temp > SecondHigest && temp != FirstHigest) { SecondHigest = temp; } } } else { SecondHigest = num; } Console.WriteLine("Second highest digit is: "+ SecondHigest); Console.ReadKey(); }

Find second largest number For example I have any number like 975846 so second largest digit is 8 Please find bellow C# program. using System;namespace ConsoleApplication1 {class Program{static void Main(string[] args){int num;int a = 0, b = 0, tmp = 0;num = 975846;a = num % 10;b = num / 10 % 10;while (num > 0){tmp = num % 10;if (a < tmp){b = a;a = tmp;}else if (a != b && b < tmp){b = tmp;}num = num / 10;}Console.WriteLine("Second largest number is b={0}", b);Console.ReadKey();}} }Output is 8

string a = "517378";int max = 0;while (a.ToString().Length > 1){max = Convert.ToInt32(a.Substring(0, 1));a = a.Substring(1, a.ToString().Length - 1);if (max > Convert.ToInt32(a.Substring(0, 1))){a = a.Remove(0, 1).Insert(0, max.ToString());}}MessageBox.Show("Second Max Num is : "+max.ToString());
