🚀 Getting Started

1. Clone the repository

git clone https://github.com/IldhanSec/simple-calculator-c.git
cd simple-calculator

2. Compile the program

Using GCC (Linux/macOS/Windows with MinGW):

gcc calcu.c -o calcu -lm

-lm is required to link the math library.

3. Run the program

./calcu

📌Noted

If you don't have a compiler like GCC, it is recommended to install it, 
otherwise the program will not run because it requires a compiler, 
if you are using Windows it is recommended to install minGw because it is one of the C language compilers.
