Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
Write C# program to swap first and last digit of a number
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class csharpExercise
{
static void Main(string[] args)
{
int num, last, first, temp, count = 0;
double swap;
// Reading number
Console.Write("Enter any number: ");
num = Convert.ToInt32(Console.ReadLine());
temp = num;
last = temp % 10;
count = (int)Math.Log10(temp);
while (temp >= 10)
{
temp /= 10;
}
first = temp;
swap = (last * Math.Pow(10, count) + first) + (num - (first * Math.Pow(10, count) + last));
Console.WriteLine("Last Digit:" + last);
Console.WriteLine("First Digit:" + first);
Console.WriteLine(num + " is swapped to " + swap);
Console.ReadLine();
}
}
Result
