Reverse Content of File Using C

# Introduction

In this lab, we will learn how to reverse the content of a file using C programming language.
We will read the content of the input file character by character, and write it back in reverse order to the output 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
