This tutorial will help us to read an integer number from the user. The user is prompted to enter any integer number. Then the entered integer is displayed to the console. Method 1: Using read and getLine function This approach uses the read and getLine function to attempt to parse the input as an integer and display the integer number to the console. Algorithm Step 1 − main :: IO () is defining the main function. Step 2 − putStrLn "Enter an integer: " prints the message asking for the user input. Step 3 − input

This tutorial will help us to find the 1's complement of the given number. The 1's complement of a binary number is found by inverting each bit of the number. A 1 becomes a 0, and a 0 becomes a 1. This is also known as the bitwise NOT operation. The 1's complement of a number can be useful in certain types of error-detecting and error-correcting Example:s, as well as in certain types of digital logic circuits. The most common use of 1's complement is in signed number representation where it's used to represent negative numbers. For example, if the ... Read More

This tutorial will help us to find the power of a number without using library function. The base value and the exponent value is passed as an argument that is used to find the exponent power of the base value passed. And the final output is displayed. For example, For base = 2 ; exponent = 3, it would return 8. Syntax power x y = product (replicate (fromInteger y) x) Product function computes a product of all elements in the list power x y = foldl (*) 1 (replicate (fromInteger y) x) Foldl takes the first item ...

This tutorial will help us in reading the height of a person and printing if the person is taller, dwarf or average height person on being compared. The height value (in centimeters) is passed as argument to the function defined and then the height is being compared with the condition defined in Haskell. And the final output is displayed. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. Step 2 − Create user defined function to perform the task Step 3 − The if-else statement is defined ... Read More

This tutorial will help us in extracting the last two digits from the given year. The year value is passed as an argument to the function defined and then the last two digits are extracted by using various methods in Haskell. And the final output is displayed. For example, For entered year = 2023, the last two digits = 23. Algorithm Step 1 − The Data.Char module is imported to use digitToInt function. Step 2 − The extractLastTwoDigits function is defined Step 3 − Program execution will be started from main function. The main() function has whole control of ... Read More

This tutorial will help us in reading the x and y coordinates and determine its quadrant. If both the coordinates are positive, the point lies in first quadrant; if x coordinate is positive and y coordinate is negative, the point lies in fourth quadrant ; if x coordinate is negative and y coordinate is positive, the point lies in second quadrant and if both the coordinates are negative, then point lies in third quadrant. Algorithm Step 1 − The quadrant function is defined using certain conditions on x and y coordinates. Step 2 − Program execution will be ... Read More

This tutorial will help us in calculating the volume and area of Sphere. The volume of a sphere is a measure of the amount of space inside the sphere. And area involves the surface area of the sphere. Method 1: Using the User-defined Function In this method, we will see two examples where we have used user-defined function with different techniques. Algorithm Step 1 − The Text.Printf module is imported. Step 2 − The volume and area functions are defined on the basis of simple mathematical formula as volume r = (4.0 / 3.0) * pi * (r ^ ...

This tutorial will help us in calculating the volume and area of the Cone. The volume of a cone is a measure of the amount of space inside the cone. And area involves the surface area of the cone that is obtained from the lateral area of a cone. The formula for the volume of a cone is V = (1/3) * π * r^2 * h, where r is the radius of the base of the cone, h is the height of the cone, and π is approximately equal to 3.14. And the formula for the surface area of ... Read More

This tutorial will help us in calculating the volume, diagonal, and area of the Cuboids. The volume of a cuboid is a measure of the amount of space inside the cuboid. And area involves the surface area of the cuboid. The diagonal of a cuboid is a line segment connecting two opposite vertices of the cuboid. It is also known as the "space diagonal" or "body diagonal" of the cuboid. Algorithm Step 1 − The volume, diagonal and area functions are defined on the basis of simple mathematical formula as volume l w h = l * w ... Read More

This tutorial will help us in calculating the volume and area of the Cylinder. The volume of a cylinder is a measure of the amount of space inside the cylinder. The area involves the surface area of the cylinder. The formula for the volume of a cylinder is the product of the base area of the cylinder, which is given by πr^2 and the height h. The formula for the surface area of a cylinder is the sum of the areas of the two circular faces and the area of the rectangular lateral surface. Algorithm Step 1 − The ... Read More
