long number = 8811191;
short max = -1;
short maxSecond = -1;
while (number > 0)
{
byte digit = (byte)(number % 10);
number /= 10;
if (maxSecond < digit)
{
if (max <= digit)
{
maxSecond = max;
max = digit;
}
else
{
maxSecond = digit;
}
}
}
Console.WriteLine(maxSecond);

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());

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
