Overlap between Objective-C and MATLAB/Octave file extensions

Question

Do Objective-C or MATLAB/Octave have source file extensions besides .m? I ask because I'm putting Hello World programs in a single folder and I can't have two hello.m files.

Answer 1

The only way I see is to create subdirectories for each of the programs and put your files there. You can tell Obj-C to treat other extensions as Obj-C, but that would not solve the problem for the other programs.

Update

To compile any extension as Objective-C, use -x objective-c on the command line or Select Objective-C from "Compile Sources As" in the target build settings. Default is "According To File Type", which means that only .m files are compield as Objective-C.

FWIW, there are many subtle differences between Objective-C++ and Objective-C. I myself would use subfolders to separate the .m files, as I already said above.
