![]() We declared the function as it takes an integer as input and returns a list of integers. Ex: Output for isPrime 13 is:įunction to generate primes from 1 to N in iterative way - function declarationĪbove function generatePrime2 generate all primes from 1 to N in a recursive way. In the function definition, we are invoking the factors function with the argument as a first parameter and comparing the returned list with a list containing two numbers one, and an argument i.e This function checks whether the factors of a number are equal to one and the number itself which is a definition of a prime number, Returns true if the number is prime else returns false. We declared a function isPrime which takes Integer as an input and returns a boolean. ![]() –- function declarationĪbove function is an utility function useful in generating prime numbers in a given range. We break the program into simpler functions.įunction to find all factors of a number. Program to Display all primes from 1 to N Implementing a function to generate all prime in a range. ![]() Implementing a function to check whether a number is prime. Note 1 is not a prime number because it has only one factor. The computations in Haskell are mathematical functions.Ī prime number is one that must have two positive factors 1 and the number itself. ![]() Haskell is a declarative, strongly typed, and functional language. This tutorial will discuss writing a program to display all prime numbers from 1 to N in Haskell Programming Language.
