WebHaskell is a statically typed, functional, and concurrent programming language with a dynamic range of packages. The show method is used to convert an int value to string. Syntax show 79 Parameter This method accepts one parameter, the int. Example main = do let x = 6 print (show x) Run Explanation We print 6, which is an integer, as a string. WebThe print function can be used to print many Haskell data types to the standard output. You could also write print integer or print string; we will discuss these sorts of polymorphic functions later. (A polymorphic function is one which operates on different types of data.)
