Beginner Projects

Build these on your own using what you learned in Level 1. Each one uses functions, vectors, maps, conditionals, and sequence functions.

1. Number Guessing Game

Pick a random number from 1 to 100 with (inc (rand-int 100)), read guesses with read-line and parse-long, say "higher" or "lower", and count attempts in a loop/recur.

2. To-Do List

Keep tasks as a vector of maps ({:title ... :done? false}). Write pure functions to add, complete, and remove tasks, and a function that prints the list numbered with map-indexed.

3. Word Frequency Counter

Split a paragraph into words with clojure.string/split, lower-case them, count them with frequencies, and print the ten most common with sort-by and take.

4. Grade Book

Represent students as maps with a name and a vector of scores, compute each average, assign a letter grade with cond, and print a report using format.

5. Unit Converter

Write functions that convert temperatures, distances, and weights, and use for to print a conversion table.
