Sure for object or library files. You won't be able to execute it.

Standard C/C++ requires that every program have exactly one main() function.  (i.e. no more and no less. (The main function cannot be overloaded.))  So in stnadard C/C++ you cannot.

Note that you don't have to have a main in every translation unit (every source code file) just one for each project that is linked into a final program.   So standard C/C++ does allow you to compile source code files that don't contain main(), however You cannot produce a final linked program from this, you can only produce object code (astatic library) that may be linked to other projects to form a final program.

However some compilers break this rule--for good reason.  Windows compilers allow you to create windows programs that have a WinMain() function instead of a main() function.  They also allow you to create DLLs that don't have a main function.
