Putting it together · ⁨모아보기⁩

One program uses several constructs

• A 9618 answer mixes DECLARE, ←, IF … THEN, FOR and OUTPUT.
• Indent the body of a loop. Put THEN on the IF line.
• A short comment with // says what a block is for.

// Total the five marks, then say whether the total reaches 20.
DECLARE Mark : ARRAY[1:5] OF INTEGER
Mark[1] ← 4
Mark[2] ← 8
Mark[3] ← 6
Mark[4] ← 2
Mark[5] ← 5
DECLARE Total : INTEGER
Total ← 0
FOR I ← 1 TO 5
  Total ← Total + Mark[I]
NEXT I
OUTPUT "Total = ", Total
IF Total >= 20 THEN
  OUTPUT "target met"
ELSE
  OUTPUT "below target"
ENDIF

What this course left for A2

• Random files, classes, enumerated types and pointers are in the full 9618 guide.
• They are assessed at A2, not in this AS course.
• The IGCSE course on this site uses the 0478 rules for 2026–2028. Do not copy those into a 9618 answer.

Now you try

• Total an array, then choose a message with IF.
