Problem X98097: Posicions senars i parelles relacionades

#include <iostream>
using namespace std;


//Pre: Un natural n
//Post: Suma xifres parells, senars i la relació
int main() {
    int n, p = 0, s = 0;

        n = n/10;
        p = p + n%10;
        n = n/10;
    }

    if (p >= s and s != 0) {
