In computer science, a type signature or type annotation defines the inputs and outputs for a function, subroutine or method. A type signature includes the function's return type, the number of arguments, the types of arguments, or errors it may pass.
In C and C++, the type signature is declared by what is commonly known as a function prototype. In C/C++, a function declaration reflects its use; for example, a function pointer that would be invoked as:
has the signature:
In Erlang, type signatures may be optionally declared, as:
For example:
A type signature in the Haskell programming language is generally written in the following format:
Notice that the type of the result can be regarded as everything past the first supplied argument. This is a consequence of currying, which is made possible by Haskell's support for first-class functions; this function requires two inputs where one argument supplied and the function is "curried" to produce a function for the argument not supplied. Thus calling f(x)
, where f :: a -> b -> c
, yields a new function f2 :: b -> c
that can be called f2(b)
to produce c

Dope sells itself, BIATCH!!!!
The real always gonna recognize the real...
If y'all muthafuckas want some
Then come get you some potna
For every city that I come to
This for every bitch that I run through
This for every hater in the Universe
Stayin' one step ahead, I'm shootin' first
For every killa lookin' for some employment
I'm a nigga that you don't fuckin' toy with
This is for my enemies and homies
If you got a strong family then join me
Everything I say, be safely said
While me and my niggas keep breakin' bread
Don't hate the Mex, it's obvious
That you don't wanna see my people prosperous
In God We Trust, put down your guns
For my niggas locked down for a thousand months
I'ma bounce and bust, sell an ounce of dust
The wetback, I suggest you get down with us
Welcome to the Dope House
Welcome to the Dope House
This is for my killas, killas, killas
This is for my killas
