Worked Solution & Example Answer:A library gives each book a code made from the first three letters of the book title in upper case, followed by the last two digits of the year the book was published - OCR - GCSE Computer Science - Question 4 - 2018 - Paper 1
Step 1
Complete the following pseudocode for a function definition that will take in the book title and year as parameters and return the book code.
Answer
01 function librarycode(title, year) 02 parta = title.subString(0, 3) 03 partb = year.subString(2, 2) 04 return parta.upper() + partb 05 endfunction
Step 2
Use pseudocode to write an algorithm that does the following : - Inputs the title and year of a book from the user. - Uses the librarycode function above to work out the book code. - Permanently stores the new book code to the text file bookcodes.txt.
Answer
- Input title from user
- Input year from user
- bookCode = librarycode(title, year)
- Open file "bookcodes.txt" for appending
- Write bookCode to file
- Close file
