Matrix Addition and Subtraction in C

# Introduction

In this lab, you will learn to perform matrix addition and subtraction in C programming language. This program will ask the user to input two matrices of the same size and then perform the addition and subtraction operation, printing the resulting matrices.

> 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
