Pascal Problem

This looks suspiciously like a homework problem.  EE experts can help you with specific questions but will not write the program for you.

Please post the code you have thus far and ask a specific question.

If you don't have any code post a word algorithm and what you think the data and functions will be.

The first decision would be, how to store the (ID,Score) pairs before sorting and printing them.

I see 2 choices, in a table, or in a list of records or objects.

The table has a maximum size limit, while the list of records is limited by available memory (but pointer operations skill is needed).

Table is a simpler solution, of course.

type concurent=record
     id,proba,punctaj:integer;
     end;

type concurenti=array[1..100] of concurent;
var records:concurenti;
    n,i:integer;


procedure writerecord(records:concurenti;n:integer);
          var i:integer;
          begin
          for i:=1 to n do
              writeln('Numar concurs: ', records[i].id, '; Proba: ', records[i].proba, '; Nota: ', records[i].punctaj, ';');
          end;

procedure readrecord(var records:concurenti;var n:integer);
          var id,proba,punctaj:integer;
          begin
          read(id,proba,punctaj);
          n:=0;
          while (id<>0) or (proba<>0) or (punctaj<>0) do
                begin
                n:=n+1;
                records[n].id := id;
                records[n].proba := proba;
                records[n].punctaj := punctaj;
                read(id,proba,punctaj);

                end;
          end;


procedure sortrecordpunctaj(var records:concurenti;n:integer);
          var i,j:integer;
              tmp:concurent;
          begin
          for i:=1 to n do
              for j:=1 to n-1 do
                  if records[j].punctaj < records[j+1].punctaj then
                     begin
                     tmp:= records[j];
                     records[j] := records[j + 1];
                     records[j + 1] := tmp;
                     end;
          end;





begin
readrecord(records,n);
sortrecordpunctaj(records,n);
writerecord(records,n);
end.

I have tested your code and seems to be working... what seems to be the problem???

Remember his is probably a school assignment so he has to follow the rules set down by the instructor.

The reason to pass the data to the procedures and functions is because they are being taught to do it that way.  It would be better to pass pointers but they haven't gotten to them yet.

Also a function or procedure should stand on its own rather than relying on the using program to provide the data and properly named.  In that way a procedure can be reused in another program.

Perhaps you are right.

But, I learned to preserve as much of the processor stack, as possible. It is a very useful habit when programming in Pascal.

Other cleaning proposition is to remove the global declaration of the variable "i". As, it is declared in every proper procedure.

So,:

var records:concurenti;
    n:integer;

instead of:

var records:concurenti;
    n,i:integer;
