Name and type of variables


Contoh program:

Var
  umur : byte;
  sekolah : string;
begin
  umur := 20;
  sekolah := 'iSTTS';
  writeln('Umurku ',umur,' tahun');
  writeln('Aku bersekolah di ',sekolah);
end.

Run and see the results! So what if we want to ask for input from the user. Use the command read or readln. Example program:

Var
  umur : byte;
  sekolah : string;
begin
  write('Umur saya berapa? '); readln(umur);
  write('Sekolah saya di mana?'); readln(sekolah);
  writeln('Umurku ',umur,' tahun');
  writeln('Aku bersekolah di ',sekolah');
  readln;
end.

Run! If you enter the input and press enter. Then, since the most recent statement asking readln program. That means we must press the enter key to return to the editor.
