Answer 1

I don't test it just write what is in my head. excuse for any syntax error

Here is online ideone demo

vector  v; 

int i = ....
while(i != 0 ){
    cout << i%10 << " - "; // reverse order
    v.push_back(i%10); 
    i = i/10;
}

cout << endl;

for(int i=v.size()-1; i>=0; i--){
   cout << v[i] << " - "; // linear
}
