Completing a pseudo-code record algorithm

Q09.2 3 marks

The incomplete pseudo-code algorithm is used to store and manage books using records. It should create a record definition called Book with the fields bookName, author and price, and create a variable for each book using that record definition.

Table 2
12author
B1B2Book
bookNameiReal
OUTPUTStringBoolean

Fill the four gaps in the record-definition skeleton using the items in Table 2. You may need to use some items more than once and will not need all the items.

Marking points

  1. 1 Has at least two correct entries among the four gaps.
  2. 2 Has at least three correct entries among the four gaps.
  3. 3 Completes all four gaps correctly for full credit.

Why this answer loses marks

I matched the field gaps but used a variable identifier where the record type is required to create the second record.

The construction gap needs the target record type; a record variable does not define what is being created.
