Hi, just started using Xcode to code C programs. Im trying to create multiple programs in the same source folder but Im getting an error message. When i select 'File' -> 'New File' -> '.C File' I can create the file fine: it creates the .c program and a header program (.h extension) But if I create this in the same source folder as another program neither will run. I know the program is fine itself, they will compile when by themselves. Whats the problem? Do I need to create a new project for each C program - I don't think I would have to otherwise XCode isn't very good. What you think?
