A function MakeString() will: 1. take two parameters: • a count as an integer • a character 2. generate a string of length equal to the count, made up of the character 3. return the string generated, or return "ERROR" if the count is less than 1. For example, the function call: MakeString(3, 'Z') will return the string "ZZZ"

Mark scheme

Marking points from the official mark scheme (May/June 2023). The mark or mark type is shown in brackets.

1. [6] FUNCTION MakeString(Count : INTEGER, AChar : CHAR) RETURNS STRING
2. [6] DECLARE MyString : STRING
3. [6] DECLARE Index : INTEGER
4. [6] IF Count < 1 THEN
5. [6] MyString ← "ERROR"
6. [6] ELSE
7. [6] MyString ← ""
8. [6] FOR Index ← 1 TO Count
9. [6] MyString ← MyString & AChar
10. [6] NEXT Index
11. [6] ENDIF
12. [6] RETURN MyString
13. [6] ENDFUNCTION
14. [6] MP1 Function heading and end including parameters and return type
15. [6] MP2 Declaration of locals Index and MyString
16. [6] MP3 Test for Count < 1 and if true, assign "ERROR" to MyString / Immediate RETURN
17. [6] MP4 Loop for Count iterations
18. [6] MP5 Use of concatenate – must have been initialised in a loop
19. [6] MP6 Return STRING (correctly in both cases)
