Finding highest value from a record

Question

I'm trying to code a procedure which goes through a record of numbers and finds which one is highest, the code currently is below. The issue I have is that it just seems to list the last score on the record (not the highest). Any help is greatly appreciated.

Procedure FindTopScore(Var TopScores : TTopScores);
Var
Count : Integer;
Highest : Integer;
Name: String;

Begin
     For Count := 1 to MaxSize Do
          If TopScores[Count].Score > Highest Then
     Highest := TopScores[Count].Score;
     Name := TopScores[Count].Name;
       Writeln('Higest score is by ' ,TopScores[Count].Name, ' of ', TopScores[Count].Score);
End;

Answer 1

You're not outputting Highest, but TopScores[Count].Score. Just use

 Writeln('Highest is ', Highest, ' for ', Name);

Also you should put the name into a variable Name inside the if-statement (it actually is outside).

Addon: If you want all names in case of a tie you can use e.g. the following code

Highest := 0;
For Count := 1 to MaxSize Do Begin
     If TopScores[Count].Score = Highest Then Begin
         Name := Name + ' and ' + TopScores[Count].Name;
     End;
     If TopScores[Count].Score > Highest Then Begin
         Highest := TopScores[Count].Score;
         Name := TopScores[Count].Name;
     End;
 End;

Answer 2

In addition to Howard's answer, set '0' to 'Highest' before beginning the loop. Being uninitialized, it is having an arbitrary value, probably higher then the highest score.

Answer 3

In addition to the accepted answer, make sure you turn on your warnings and hints, and you'll see:

      testhighest.pp(16,39) Warning: Local variable "Highest" does not seem to be initialized

which is the

        If TopScores[Count].Score > Highest Then
