Tuples/records are like Cartesian product, because each value of a tuple or record contains a value from each of many underlying sets. Cartesian product is usually written with a product operator, \(\times\) or \(\Pi\).
27 lip 2021 · TL;DR; Stop trying to access directly the n -th element of a t -uple and use a record or an array as they allow random access. You can grab the n -th element by unpacking the t -uple with value deconstruction, either by a let construct, a match construct or a function definition: let ivuple = (5, 2, 1, 1) let squared_sum_let = let (a,b,c,d) = ...
To access specific elements of a tuple without binding them to variables, you can use indexing. Indexing in OCaml starts from 0, so the first element can be accessed with index 0, the second with index 1, and so on.
core v0.17.1 (latest): Industrial strength alternative to OCaml's standard library
Alternatively, you can access tuple elements using indexing. Indexing in OCaml starts from 0. Here's an example: ```ocaml let my_tuple = (3, "OCaml", true) let first_element = fst my_tuple let second_element = snd my_tuple print_endline ("First element: " ^ string_of_int first_element) print_endline ("Second element: " ^ second_element) ```
To access individual elements of a tuple, you can use pattern matching or indexing. Let's consider the following tuple: ```ocaml let my_tuple = (1, "hello", 3.14) ```
2 sty 2010 · A tuple is another kind of type in OCaml that programmers can define. Like records, it is a composite of other types of data. But instead of naming the components, they are identified by position. Here are some examples of tuples: A tuple with two components is called a pair.
