15-minute session: read for 3 minutes, trace for 3, experiment for 7, and complete the check for 2. Spend longer whenever you need.
A useful test compares a result with a requirement. The planner must never report negative remaining work for its stated nonnegative input domain. Run the starter, then deliberately remove the protection for completed counts above total. At least one check should fail. Restore it. Add two named study tasks, a summary, and boundary cases. Save the source and evidence on Agila Forge. Explain every line, including anything suggested by AI.
begin and end enclose statements. := assigns; = compares. The final program terminator is end.. This course uses Free Pascal in Object Pascal mode while starting with procedural constructs.
program AgilaStudy;
{$mode objfpc}{$H+}{$assertions on}
function Remaining(Total, Done: Integer): Integer;
begin
if Done >= Total then Result := 0 else Result := Total - Done;
end;
begin
Assert(Remaining(4,1)=3);
Assert(Remaining(4,4)=0);
Assert(Remaining(4,5)=0);
Assert(Remaining(0,0)=0);
writeln('Passed');
end.
Expected result: Passed
Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.
