I coding interview for c++, Topic name’s Sliding window

using namespace std;

int main() {
  unordered_map<string , unsigned int> map;
  string s =  "barfoothefoobarman";
  vector<string> words =  {"bar","foo","mannn"} ;
  vector<int> result;
  unsigned int length = words[0].size();

  map.clear();
  for(const string & word : words) {
      map[word]++;

  }
  //iterate
  for(unsigned int offset = 0 ; offset < length; offset++) {
      //silding window size
      unsigned size = 0;
      unordered_map<string,unsigned int> seen;
      for(unsigned int i = offset; i + length <= s.size(); i += length) {
          cout<<endl<<i<<" |"<<endl<<offset<<endl;
          string sub = s.substr(i, length);
          //if the word absent int the reference map
          // clear silding window and move on
          auto itr = map.find(sub);
          if(itr == map.end()) {
              cout<<"Not f:  "<<sub<<endl;
              size = 0;
              continue;
          } else {
              cout<<"found : "<<sub<<"t"<<map[sub]<<endl; // map[sub] is counter occurrences

          }
          //Increase
          seen[sub]++;
          cout<<"Seen :"<<seen[sub]<<endl;
          size++;
          // To make sure the silding window is valid
          // We need to check only recent occurence
          // againts the reference
          // because previous occurence
          // were checked on previous iterations
          cout<<seen[sub]<<"t seen and itr t"<<itr->second<<endl;
          while(seen[sub] > itr -> second) {
              // If the occurrences amount exceeds
              // the reference amount,
              // we shrink the window from the left until
              // the window becomes valid again.
              // A word at the beginning of the current sliding window.
              string first = s.substr(i - (size - 1) * length, length);
              cout<<"Size-1 * length :"<<(size-1)*length<<endl<<"First :"<<first<<endl;
              // remove the occurrence from the window
              // skrinking it from the left
              --seen[first];
              --size;
              // need to calculate the begining
              // index of the current sliding window
              if(size == words.size()) {
                  cout<<"oke";
                  result.push_back(i-(size-1)*length);
              }

          }

      }
  }
  for(int i : result) {
      cout<<"result : "<<i<<endl;
  }


}

I encounter problem in the result, it indicates a variable’s result.

I try run code, which successfully complier

But not result my result hope doing true

Don’t run a success
