# 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
