Check if the value entered is palindrome or not using C language

CServer Side ProgrammingProgramming

A palindrome is nothing but any word, number, sentence, or other sequence of characters that reads the same backward as forward.

In this programming, we are trying to enter a number from console, and assign that number to temp variable.

If number is greater than zero, apply the logic given below −

while(n>0){
   r=n%10;
   sum=(sum*10)+r;
   n=n/10;
}

If temp=sum, then the given number is a palindrome. Otherwise, it is not a palindrome.

Example

Following is the C program for verification of a value being palindrome −

#include<stdio.h>
#include<conio.h>
void main(){
   int n, r, sum=0, temp;
   printf("Enter a number: ");
   scanf("%d",&n);
   temp=n;
   while(n>0){
      r=n%10;
      sum=(sum*10)+r;
      n=n/10;
   }
   if(temp==sum)
      printf("It is a palindrome number!");
   else
      printf("It is not a palindrome number!");
   getch();
}

Output

When the above program is executed, it produces the following result −

12345
It is not a palindrome number
