This introduction covers Working with Text within String Handling for GCSE Computer Science. Revise String Handling in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 8 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 2 of 7 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
Working with Text
Strings are everywhere - names, addresses, passwords, messages. String handling is the art of manipulating text. Need to extract the first 3 characters? Check if an email contains "@"? Convert to UPPERCASE? Concatenate first name and surname? These operations are essential for any program that deals with text!
Practice questions for String Handling
The string variable word = "Hello". What does word.length return?
Explain the purpose of the ASC() and CHR() functions in OCR pseudocode. Give one reason a programmer might need to convert between characters and their ASCII codes.
