I want to find whether a number is palindrome or not if not i have to find the very next number which is palindrome please help

Question

#include <iostream>
using namespace std;

int palind(int a){
int b=0;
while(a>0){
b=b*10+a%10;
a/=10;}
if(a==b)
return a;
else
return palind(a+1);
}

int main() {
int s;
cin>>s;
cout<<palind(s);
return 0;
}

this code isn't working please help me fixing it
what's wrong with the above code?

Answer 1

Maybe this?

#include <iostream>
using namespace std;

bool isPal(unsigned n) {
unsigned dig, rev=0, _num;
_num=n;

while(n!=0) {
dig=n%10;
n/=10;
rev=rev*10+dig;
}

if(rev==_num)
return true;
else
return false;
}

int main() {
unsigned num;
cin>>num;
if(isPal(num))
cout<<"Your number is a palindrome";
else {
cout<<"Your number is not a palindrome"<<endl;
for(unsigned i=num+1; i<=2*num; i++) {
if(isPal(i)) {
cout<<"Next number that is a palindrome is "<<i;
break;
}
}
}

return 0;
}
