Question

HTML

Hello!
I can’t find any information on how to read numbers separated from each other by an arbitrary number of spaces and newlines.

var n: integer;
...
while not seekeof do
begin
   read(n);
   ...
end;

Doesn't work, error 201. Please help!

Answer 1

Everything is extremely simple:

program sample;
    var a, b, c: integer; //В этом примере три числа, все целые
begin
    readln(a, b, c);
    {сюда можно ещё что-то написать, например, вывод суммы введённых чисел}
    readln;
end;

If something is not clear, does not work or does not work properly - write :)
