Hello everyone, I'm in need of assistance regarding errors during the uploading process for my Fingerprint Scanner college project. I had no prior knowledge with coding and the project I have chosen required it to function. Considering that making a code from scratch isn't mandatory for my college project I used Electronic Tech's (Video Link: https://www.youtube.com/watch?v=Lo7BQVSx5zM&list=PLKjIJzQ5TzAFZMXoVyB3nQianIhFMUlrz&index=5) Biometric Attendance System instead. I believe all of the components are all in order, its just that an error occurs when uploading.
Here are the error log:

Compilation error: control reaches end of non-void function [-Werror=return-type]
I was finding solutions for the "control reaches end of non-void function [-Werror=return-type]" but I was unsure if the solutions given applied to my project aswell. Considering I have no knowledge with coding I'm worried I would screw up the code as a whole.
Here is the entire code I am using for my project from Electronic Tech:
