It is now used to develop software in many other application areas. OCaml is a functional programming language: there is no restriction on the definition and use of functions. Moreover, the memory manager is incremental: it runs in parallel with the application, so that garbage collection does not cause noticeable delays. The following code example defines a recursive function sum that accepts one argument xs. Officially supported platforms are described hereand other platforms are supported by the community.
Partial function applications and currying; What is functional programming . the same arguments, the compiler only needs to actually call the function once.
Safety; Functions; Imperative features; Error recovery; Data Types; Aptness to Fast, Flexible and Functional Programming with OCaml, Gemma Gordon and Anil In addition to its bytecode compiler, OCaml offers a compiler that produces. OCaml is a functional programming language.
The key linguistic abstraction of The compiler automatically figures out most types. This can make the code.
The following code calculates the Fibonacci sequence of a number n inputted.
In other words, functions are ordinary values: a function can be passed as an argument to a function or returned by a function.
What is OCaml – OCaml
Its static type system prevents runtime type mismatches and thus obviates runtime type and safety checks that burden the performance of dynamically typed languages, while still guaranteeing runtime safety, except when array bounds checking is turned off or when some type-unsafe features like serialization are used. Strictness vs laziness C-derived and ML-derived languages are strict. Beyond these powerful built-in types, OCaml offers powerful means of defining new data types: records, enumerations, and sum types.
Haskell and Miranda are non-strict, or lazy, languages. Aside from type-checking overhead, functional programming languages are, in general, challenging to compile to efficient machine language code, due to issues such as the funarg problem.

It extends Caml with object-oriented features, and is a member of the ML OCaml unifies functional, imperative, and object-oriented programming. Functional Reactive Programming is a model for programming that tries to adapt state-heavy programming such as UIs or games to the functional programming.
Assignments There will be one assignment every one or two weeks.
Under some circumstances, significant speedups are possible using multistage programming, because more detailed information about the data to process is available at runtime than at the regular compile time, so the incremental compiler can optimize away many cases of condition checking, etc.
Each pair should write up solutions themselves. One term which you'll hear a lot when discussing functional languages is "boxed". May Learn how and when to remove this template message. Going back to the original definition, let's "fill in" the first argument a setting it to 2 to get:.
Introduction. Features of Functional Programming Languages features. Compiler and run-time system that makes OCAML programs run with.
They allow side-effects through things like references and arrays, but by and large most of the code you'll write will be pure functional because they encourage this thinking.
In the case of strlen yes, in other cases, probably not. It is now used to develop software in many other application areas.

In OCaml, the basic types are all unboxed. OCaml features pattern matching, a generalization of the traditional case analysis construct.
