Q14) Write a program in C to input a number and check if it is a palindrome number or not using while loop.
Palindrome numbers are such numbers whose reverse is same as the original number. Example, 121, 14541, 22 etc.
Program
#include <stdio.h>
#include <conio.h>
int main()
{
int n,d,on,rev=0;
printf("Enter any number ");
scanf("%d",&n);
on=n; // storing the original number
while(n>0)
{
d=n%10;
rev=(rev*10)+d; // reverse the number
n=n/10;
}
if(on==rev)
{
printf("Palindrome Number");
}
else
{
printf("Not Palindrome Number");
}
return 0;
}Output
Enter any number 14541 Palindrome Number
