Understanding Arrays in pseudocode in VCE Pseudocode

What it does: This is exactly how a 5-element integer array is declared. This loop visits each index from 1 to 5 in turn. Square brackets are used to access array elements. The ← symbol assigns a value, just like with normal variables. END FOR closes a FOR loop block correctly. A FOR loop with the array's size lets you visit every element. By convention, indexing starts from 1, not 0. This line stores 10 at index 1 of the scores array.

Common mistakes: Arrays are declared with DECLARE, not ARRAY, in VCAA pseudocode. Array elements use square brackets, not round brackets.

Quick Questions

1. Do array elements use square brackets like scores[1]?
A. No
B. Yes ✓
Square brackets are used to access array elements.
2. Is round-bracket syntax like scores(1) valid for arrays?
A. No ✓
B. Yes
Round brackets aren't used for array indexing in pseudocode.
3. Does DECLARE scores[5] OF INTEGER declare an array of 5 integers?
A. Yes ✓
B. No
The number in brackets sets how many elements the array holds.
4. Is the ← arrow used to assign values to array elements?
A. Yes ✓
B. No
The ← symbol assigns a value, just like with normal variables.
5. Does a FOR loop over an array end with END FOR?
A. No
B. Yes ✓
END FOR closes a FOR loop block correctly.

Match the Pairs

scores[1] ← 10 → Assigns the value 10 to the first array element
DISPLAY scores[i] → Prints the value stored at index i in the array
Declares an array of 5 integers named scores → DECLARE scores[5] OF INTEGER
Loops through every index in the array → FOR i FROM 1 TO 5
scores(1) ← 10 → Wrong - array elements use square brackets, not round
DECLARE scores OF INTEGER → Wrong - array declarations need a size in brackets

Key Term

scores[1]
Accesses the array element at index 1, using square brackets to specify the position.

Fill in the Blanks

1. DECLARE scores[5] OF INTEGER
Hint: Type the data type stored in the array.
2. DISPLAY scores[i]
Hint: Type the loop variable used as the index.
3. FOR i FROM 1 TO 5
Hint: Type the starting index number used when looping through an array.
4. DISPLAY scores[2]
Hint: Type the keyword used to output a value.
5. DECLARE scores[5] OF INTEGER
Hint: Type the number of elements the array holds.

Spot the Error

Question 1
A ARRAY scores[5] OF INTEGER
B scores[1] ← 10
C DISPLAY scores[1]
Line A — Arrays are declared with DECLARE, not ARRAY, in VCAA pseudocode.
Question 2
A DECLARE scores[5] OF INTEGER
B scores(1) ← 10
C DISPLAY scores[1]
Line B — Array elements use square brackets, not round brackets.
Question 3
A DECLARE scores[5] OF INTEGER
B scores[1] ← 10
C DISPLAY score[1]
Line C — The array name is misspelled - it should be scores, not score.
Question 4
A DECLARE scores[5] OF INTEGER
B FOR i FROM 1 TO 5
C DISPLAY scores[i]
D END LOOP
Line D — A FOR loop must close with END FOR, not END LOOP.
Question 5
A DECLARE scores OF INTEGER
B scores[1] ← 10
C FOR i FROM 1 TO 5
D DISPLAY scores[i]
Line A — An array declaration needs a size in square brackets, like scores[5].
