Find Largest and Smallest Numbers Using Global Variables

# Introduction

In this lab, we will learn how to find the largest and smallest numbers among two input numbers using global declaration in C programming. Unlike local variables, global variables can be accessed and modified by any function within the program. We will use global variables to store the input numbers and solve the problem.

> 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
