## Overview

This repository is a collection of standalone C exercises rather than a single application. The principal workflow is a caller supplying values, strings, or command-line arguments to an exercise routine, which computes a value or writes output. The tree shows capabilities across formatted output, pointers and arrays, string operations, conversion and mathematics, argument handling, and allocation. No README is present; sampled files establish only a few internal calls, so the graph avoids inferring wiring between exercises.

Main entry points: [`c00/ex00/ft_putchar.c`](https://github.com/el-montasir/piscine-1337/blob/main/c00/ex00/ft_putchar.c) (Character and sequence output), [`c00/ex05/ft_print_comb.c`](https://github.com/el-montasir/piscine-1337/blob/main/c00/ex05/ft_print_comb.c) (Combination output), [`c00/ex07/ft_putnbr.c`](https://github.com/el-montasir/piscine-1337/blob/main/c00/ex07/ft_putnbr.c) (Integer output), [`c04/ex04/ft_putnbr_base.c`](https://github.com/el-montasir/piscine-1337/blob/main/c04/ex04/ft_putnbr_base.c) (Base number output)
