# C00

#### Objective:

The goal of this project is to learn basic programming concepts in C. You’ll implement small functions that teach you syntax, data types, control flow (loops, conditionals), and basic I/O (input/output).

#### What you'll learn:

* Writing your first functions in C.
* Understanding basic data types (`int`, `char`, `float`, etc.).
* Working with loops and conditionals.
* Understanding the importance of functions and prototypes.
* Getting familiar with the compilation process.
* Using `git` for version control.
* **Problem-solving:** Each exercise will help you break down larger problems into smaller, manageable pieces.

#### Key Exercises and Concepts:

## Contents

1. Exercise 00: ft\_putchar
2. Exercise 01: ft\_print\_alphabet
3. Exercise 02: ft\_print\_reverse\_alphabet
4. Exercise 03: ft\_print\_numbers
5. Exercise 04: ft\_is\_negative
6. Exercise 05: ft\_print\_comb
7. Exercise 06: ft\_print\_comb2
8. Exercise 07: ft\_putnbr
9. Exercise 08: ft\_print\_combn
10. Submission and Peer-Evaluation

***

#### In short:

C00 is all about getting comfortable with the C language and the basic programming concepts you’ll need for more advanced projects. It’s very hands-on, and by the end, you’ll have a solid foundation in C programming and problem-solving skills that will serve you for the rest of the 42 curriculum.
