Worked Solution & Example Answer:A program creates usernames for a school - OCR - GCSE Computer Science - Question 4 - 2023 - Paper 1
Step 1
State, using the process in Fig. 2, the username for Rebecca Ellis.
Answer
To create the username for Rebecca Ellis using the process in Fig. 2:
- First, take the first three letters of the first name 'Rebecca', which gives 'Reb'.
- Next, take the first two letters of the surname 'Ellis', which provides 'El'.
- Combine these two parts to create the username: 'RebEl'. Thus, the username for Rebecca Ellis is RebEl.
Step 2
What would be the username for a teacher called Fred Biscuit using the updated process?
Answer
For the teacher 'Fred Biscuit', we use the updated username creation process:
- Take the last three letters of the surname 'Biscuit', which gives 'uit'.
- Then, take the first two letters of the first name 'Fred', which gives 'Fr'.
- Combine these parts to arrive at the username: 'uitFr'. Hence, the username for Fred Biscuit is uitFr.
Step 3
Write an algorithm for the updated program design shown in question 4(b)(i).
Answer
Algorithm for creating the username for a teacher:
- Start
- Input teacher's first name (Fred)
- Input teacher's surname (Biscuit)
- Set username = last three letters of surname + first two letters of first name
- username = 'uit' + 'Fr'
- Output username
- Stop
