A program to input a number and print its reverse.

For Doing this you may run a 'for' loop. and doing mod by 10.
here is the code:

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

namespace reverse
{
class Program
{
static void Main(string[] args)
{
int a, b;
a = int.Parse(Console.ReadLine());
for(int i=a;i>0;i=i/10)
{
b = i % 10;
Console.Write(b);
}
Console.ReadLine();

}
}
}

C# Programming how to know that the number is Armstrong or not..?.

For Doing this you may run a 'for' loop. and doing mod by 10.
here is the code:

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

namespace reverse
{
class Program
{
static void Main(string[] args)
{
int num, sum, y;
Console.WriteLine("Please write the number to know")
num=int.Parse(Console.ReadLine());
for(int i=num;i>0;i=i/10)
{
y=i%10;
sum=sum+y*y*y;
}
if(sum==num)
{
Console.WriteLine("Armstrong");
}
else
{
Console.WriteLine("Not Armstrong");
}
Console.ReadLine();

}
}
}

armstrong numbers are just like - 153 = 1*1*1 = 1 , 5*5*5 = 125, 3*3*3 = 27
1+125+27=153

print the sum of number you type
Print the number one by one...

class Program
{

static void Main(string[] args)

{

int sum = 0,a,b;
a=int.Parse(Console.ReadLine());
for (int i = a; i > 0;i= i / 10)

{

b = i % 10;
sum = sum + b;

}

Console.WriteLine(sum);
Console.ReadLine();

}
}


For Example You type 123 it returns 6 as answer.. 1 + 2 + 3 = 6

A program to input a number and print its factorial.

Factorial exapmle like you type 5 for its factorial:
5*4=20*3=60*2=120*1= 120

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

namespace reverse
{
class Program
{
static void Main(string[] args)
{
int num, fact=1;
num = int.Parse(Console.ReadLine());
for(int i=num;i>=1;i--)
{
fact=fact*i;
}
Console.WriteLine("factorial is {0}",fact);
Console.ReadLine();

}
}
}
