Write a program to enter a no. and check it is palindrome prime or not.

#include<stdio.h>

#include<conio.h>

void main()

{

        int i, n, on, rem, revno=0, k=1;

        clrscr();

printf(“Enter any no. : ”);

scanf(“%d”, &n);

for(i=2;i<=n/2;i++)

{

if(n%i==0)

                {

                                k=0;

                                break;

}

}

on=n;

while(n>0)

{

                rem=n%10;

                revno=(revno*10)+rem;

                n=n/10;

}

if(revno==on && k==1)

printf(“%d is a palindrome prime no.”, on);

else

printf(“%d is not a palindrome prime no.”, on);

getch();

}

OUTPUT :

Enter any no. : 131

131 is a palindrome prime no.
