In the following example, we will check whether the given number (121) is a Palindrome number or not.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int num =121;
int copyNum = num;
int reverse =0;
// reverse a numberwhile(copyNum !=0)
{
reverse = reverse *10;
reverse = reverse + (copyNum %10);
copyNum = copyNum /10;
}
// resultif(num == reverse)
Console.Write("{0} is a palindrome number", num);
else
Console.Write("{0} is not a palindrome number", num);
}
}
}
Output
121 is a palindrome number
Palindrome Numbers between the Given Range
In the following example, we will find all the Palindrome numbers between 10 and 50.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int start =10;
int end =50;
int copyNum =0;
int reverse =0;
int flag =0;
Console.WriteLine("Palindrome numbers between {0} and {1}: ", start, end);
for(start=start; start<=end; start++)
{
copyNum = start;
reverse =0;
// reverse a numberwhile(copyNum !=0)
{
reverse = reverse *10;
reverse = reverse + (copyNum %10);
copyNum = copyNum /10;
}
// resultif((start == reverse) && (start !=0))
{
flag =1;
Console.Write(start +" ");
}
}
if(flag ==0)
Console.Write("There is no palindrome number between the given range");
}
}
}
Output
Palindrome numbers between 10 and 50:
11 22 33 44
Check Whether the Given Number is Palindrome or Not
In the following example, we will check whether the given number is a Palindrome Number or Not.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
Console.Write("Enter a (int) Number: ");
int num = Convert.ToInt32(Console.ReadLine());
int copyNum = num;
int reverse =0;
// reverse a numberwhile(copyNum !=0)
{
reverse = reverse *10;
reverse = reverse + (copyNum %10);
copyNum = copyNum /10;
}
// resultif(num == reverse)
Console.Write("{0} is a palindrome number", num);
else
Console.Write("{0} is not a palindrome number", num);
}
}
}
Output
Enter a (int) Number: 52
52 is not a palindrome number
Reminder
Hi Developers, we almost covered 90% of String functions and Interview Question on C# with examples for quick and easy learning.
We are working to cover every Single Concept in C#.
