Program to List Files in Directory

# Introduction

In this lab, we will create a C program to list all the files present in a directory using the `dirent.h` header file.

> Note: You need to create the file `~/project/main.c` yourself to practice coding and learn how to compile and run it using gcc.

cd ~/project
# create main.c
touch main.c
# compile main.c
gcc main.c -o main
# run main
./main
