Question

 struct WeatherStation  {

string Name;
double Temperature;

 };

 void Initialize(WeatherStation[]);
 void HL(WeatherStation List[]);

int main()

 {
 string Command;
  WeatherStation Stations[5];

  //some commands

 }
 void Initialize(WeatherStation StationList[])

 {

  StationList[0].Name = "A";
  StationList[0].Temperature = 0.0;

  StationList[1].Name = "B";
  StationList[1].Temperature = 0.0;

  StationList[2].Name = "C";
  StationList[2].Temperature = 0.0;

  StationList[3].Name = "D";
  StationList[3].Temperature = 0.0;

  StationList[4].Name = "E";
  StationList[4].Temperature = 0.0;

  }

 void HL(WeatherStation List[])
  {
   int K;
   int Low = List[0];            
   int High = List[0];       

   for(K = 0 ; K < 5 ; K++)      
    if(List[K] < Low)
    Low = List[K];

   for(K=0 ;  K < 5 ; K++)    
    if(List[K] > High)
    High = List[K];

   cout << "Lowest Temperature:  " <<Low << endl;
   cout << "Highest Temperature: "<< High << endl;
   } 

The last part is tripping me up.

Answer 1

It cannot convert WeatherStation to int because WeatherStation is a structure. If you want to get a member of a structure you should write, for instance, List[0].Temperature.
