As the error says , you have two mains in two different files.
Rename the one you do not need into something else like main_old

Thank you very much for your quick response. I want to work with file and folders on replit for better organize. How to run an individual file in an individual folder. like:

Module-1 >
File-1 > program-1.c I want to run it individually
File-2 > program-2.c I want also run it individually

When I create and run files like this, that errors occurs please help me. Thanks

Well, C only allows for one main when you compile it.
So you need to compile the programs separately, I would compile by hand in the shell with the -c filename option

Thanks for your help. I’m working according to your instructions and understood. This program crashed here but works another well. Why so much errors in replit.

I added an image and showed my errors I’m facing. Thank you.
