Haskell Program to Display Fibonacci Series
This tutorial discusses writing a program to display Fibonacci Series in the Haskell programming language. The Fibonacci series is a sequence in which each number is the sum of the preceding two terms. The Fibonacci series up to five terms is 0 1 1 2 3. In this tutorial we see, Program to print nth fibonacci number. Program to print the first ‘n’ terms in the Fibonacci series. Program to print the first ‘n’ terms in the Fibonacci series using the list comprehension. Program to print the first ‘n’ terms in the Fibonacci series using the map function. ...

This tutorial discusses writing a program to print the multiplication table in the triangular form in the Haskell programming language. For example, the multiplication table for the number 10 in the triangular format is 1 2 4 3 6 9 4 8 12 16 5 10 15 20 25 6 12 18 24 30 36 7 14 21 28 35 42 49 8 16 24 32 40 48 56 64 9 18 27 36 45 54 63 72 81 10 20 30 40 50 60 70 80 90 100 Algorithm Steps Take input or initialize an integer variable ...
Read MoreHaskell Program to Swap Two Numbers
This tutorial discusses writing a program to swap two numbers in the Haskell programming language. Variables are immutable in Haskell i.e once declared their values cannot be changed. So we cannot swap the values of two variables, but we can mimic this by swapping values in a list and tuple. In this tutorial we see, Program to swap two numbers in a binary tuple. Program to swap two numbers in a list. In Haskell, tuples are used to store elements of different data types as a collection. Tuples are identified by parenthesis at the ends. Tuples support only ...
Read MoreHaskell Program to determine the name and version of the operating system
This tutorial discusses writing a program to find the operating system info in the Haskell programming language. Haskell provides functions to find the system info. These functions can be accessed by importing the Info module from the System package in Haskell. In this tutorial, we see Program to display the name of the Operating System. Program to display the architecture of the processor. Program to display the compiler name. Program to display the compiler version. Syntax To import a module in Haskell the syntax is to follow. import packageName.moduleName To import the Info module from the system ...
Read MoreHaskell Program To Perform nCr (r-combinations)
This tutorial discusses writing a program to perform nCr combinations in the Haskell programming language. The nCr is used to find the number of ways r items can be selected from n items given that order doesn’t matter. The nCr is defined as n! / ( r! (n-r)! ). For example number of ways in which 3 items can be selected from 5 items is 5! / ( 3! (5-3)! ), i.e 10 ways. In this tutorial we see, Program to find the factorial of a number (helper function to find the nCr combinations). Program to find the ...
Read MoreHaskell Program to Find the Perimeter of a Circle
This tutorial discusses writing a program to find the perimeter of a circle in the Haskell programming language. The perimeter of the circle is the length of the boundary of the circle. The perimeter of a circle is also called the circumference. The perimeter of a circle is defined as 2*pi*r where r is the radius of the circle. For example area of the circle with a radius of 4 units is 25.13274 (2*pi*4). In this tutorial, we see two ways to implement a program to find the perimeter of a circle. Program to find the perimeter of ...
Read MoreHaskell Program to Find the Area of a Trapezium
This tutorial discusses writing a program to print the area of a trapezium in the Haskell programming language. A trapezium is a quadrilateral with one opposite side parallel. The above figure is a trapezium. The length of one of the parallel sides is denoted by a and the other side is denoted by b. The height of the trapezium is denoted by h. The area of a trapezium is defined as (a+b)/(2*h), where a and b are the lengths of the parallel sides and h is the height or distance between the parallel sides. In this tutorial, we see ...
Read MoreHaskell Program to Calculate the Power of a Number
This tutorial discusses writing a program to calculate the power of a number in the Haskell programming language. The nth power of a number is the value when the number is multiplied by itself n times. The power of numbers can be expressed in exponential forms “a^n”, a is raised to the power of n. Here a is called the base and n is called an exponent. For example, 2 raised to the power of 5 is 2^5 i.e 32. In this tutorial, we see different ways to implement a program to calculate the power of a number. Program ...
Read MoreHaskell Program to Count Number of Digits in an Integer
In this tutorial, we discuss writing a program to count the number of digits in an integer in the Haskell programming language. In this tutorial, we see three ways to implement a program to count digits in Haskell. Program to count the number of digits in an integer. Program to count the number of digits in an integer using if-else.Program to count the number of digits in an integer using the length function. Algorithmic Steps Take input or initialize a variable for an integer. Implement the program logic to count the digits in an integer. Print or display ...
Read MoreHaskell Program to Reverse a Number
This tutorial discusses writing a program to reverse a number in the Haskell programming language. In this tutorial, we see two ways to implement a program in Haskell to reverse a number. Program to reverse a number using the list function reverse. Program to reverse a number using a recursive function. Example 1 Program to reverse a number using the list function reverse. -- function declaration reverseNumber :: Int->Int -- function definition reverseNumber n = k where temp = reverse (show n) ...
