Functional Programming in C

Implementation of functional programming primitives (map, filter, reduce, etc.) in pure C, using generic lists and variadic functions — without loops in task files.

Overview

This project re-creates higher-order functions like those in JS or Haskell using:

• Function pointers and generic data structures
• Variadic argument handling (stdarg.h)
• Memory-safe operations via destructors

Language: C | Environment: Linux / GCC

---

Features

• for_each, map, filter, reduce
• Variadic: map_multiple, reduce_multiple, for_each_multiple
• Tasks using these functionals:
  • Reverse integer list
  • Filter students by grade
  • Compare list sums
  • Generate square matrix

Usage

make               # build project
./install.sh       # optional checker setup
hw_checker --legacy
