k-and-r-solutions

This repository features solutions to the exercises of the book The C Programming Language, by Brian W. Kernighan and Dennis M. Ritchie (K & R).

Running the exercises

# All exercises
./run

# Exercises in a specific chapter
./run 1

# Specific exercise, eg 1-5
./run 1 5

Each exercise features a docblock at its top, featuring:

• The @description of the exercise
• For some exercises: an @interactive annotation

Interactive exercises will be skipped when running multiple exercises at once (eg all exercises in a chapter). Non-interactive exercises usually feature automated tests that check their correctness, for example:

• Single exercise results
  

• Multiple exercises result summary
  

Hint: for interactive exercises, press Ctrl + D to write EOF in the terminal. In K & R exercises, this is used as a signal that user input has finished.
