Step-by-step explanation:
The data structure type student = {name : string; year : int} is an example of a record or a structure in programming. It is a way to organize and store related pieces of information.
In this case, the record or structure has two fields: name and year. The name field is of type string, which means it can store a sequence of characters (e.g., a student's name). The year field is of type int, which means it can store a whole number (e.g., a student's academic year).
