Is it possible to run c++ program compiled by any compiler in any platform?

Question

Is it possible to run c++ program compiled by any compiler in any platform(Windows,Mac,Linux)?If no, have I use different code/compiler for same process in different platforms?

Please forgive me for asking a basic level question.

Thank you in advance

Answer 1

The compiler you use must be meant for the platform you target. You could use a compiler from the same vendor to do multiple platforms, but each platform must be compiled separately.
