What's The Logic To Find The Given Number Is Palindrome Or Not In C++ Language?

Just for fun.....

#include
#include
using namespace std;

int main ()
{   
int x;
string n,mem,inverse="";
    cin >> n;
mem=n;
x=n.size();

   while (x>0)
   {
   inverse=inverse+n.substr(x-1);
   n.erase(x-1,x);
   x--;
   }

cout
