this code:

#include <iostream>  using namespace std;  int main() {      double value, maxvalue, index;      cin >> value;     maxvalue = value;     index = 1;      (int = 2; <= 10; i++) {         cin >> value;          if (value > maxvalue&&value<0) {             maxvalue = value;                 index = i;         }      }     cout << "max value = " << maxvalue << " index = " << index << endl;   }
