How to Get Started

This project uses a Makefile to simplify compilation. You no longer need to run gcc manually for each file.

1. Clone the Repo:

   git clone https://github.com/TheTimelessRecall/C-Odyssey.git
   cd C-Odyssey

2. Compile the Code: You can compile all programs at once or just a specific one.

   • Compile all programs:

     make all

   • Compile a single program (e.g., bmi_cal.c):

     make bin/bmi_cal

   All compiled programs will be placed in a bin/ directory.

3. Run an Executable:

   ./bin/bmi_cal

4. Clean Up (Optional): To remove all compiled files, run:

   make clean
