Haskell Exercises for Beginners

Explore running Haskell code online or locally and build a Hello World program with a main function and do notation to print a name, date of birth, and mobile number.

Write a hello world style program that prompts for your name, reads keyboard input with getLine, and outputs a personalized greeting by concatenating the name with greeting text.

Develop a basic Haskell program that prompts the user for their job and location, reads keyboard input in main, and prints the collected information with proper spacing.

Create a Haskell program that outputs the letter L, using either multiple string line calls with proper capitalization or a single function call with a newline to compress the code.

Print variable values in Haskell by defining immutable variables, then output strings with the appropriate function and numbers with a separate function, including multiple variables x, y, z.

Build a Haskell bmi calculator that computes bmi as weight divided by height squared, reads doubles from keyboard with a getDouble function, and shows hardcoded values.

Apply a simple Haskell solution that reads hourly rate and hours worked with a custom input function, then outputs the total revenue, demonstrating numeric input handling.

Define X, Y, and Z with ranges 1 to 10, 100s, and 1000s; use let bindings to print numbers up to 100, and show how to disable code with comments.

Learn to implement a two-argument maximum function in Haskell, using if X < Y then Y else X; test with 6 and 9, and rename to Mexi to avoid conflicts.

Define a square function in Haskell that computes x times x, define its data types, and show how doubles or integers can be used to represent the result.

Define functions to double and triple a number, compose them into a double function, apply to a parameter x to show outputs, and present the exercise solution.

Define a list and extract its first and second elements using the !! operator with zero-based indexing.

Solution 13 demonstrates using a Haskell list comprehension to multiply every element by three, showing with numbers like 2,4,6,8,10,12 and that any factor can be applied.

Learn to iterate over a list of names in Haskell by defining the list and applying map to transform each name into a string, then run to view the list.

Learn to output a multiplication table in Haskell by converting numbers to text with show, concatenating with the ++ operator, and printing the computed products for a chosen multiplier.

Learn to print numbers from one to end using a for loop in Haskell, after importing control bonus points and repeating one or more lines of code.
