This unit introduces pupils to the new data structures of records and dictionaries. They will develop a Caesar cipher encryption program using a dictionary as a cipher wheel. Pupils will explore how data can be read from and written to files and how this data can be used within a program.

Programming: dictionaries and data files

Match the file operations with their descriptions:
