C code file extension What is the difference between cc and cpp closed

Question

C++ code has been saved as both.cc and.cpp files. Is there a distinction between the two?

The Google style guide appears to suggest.cc, but no rationale is provided. I'm mostly interested in apps that run on Linux platforms.

Answer 1

GNU GCC recognizes all of the following as C++ files and will utilize C++ compilation whether invoked with gcc or g++:

C, C++, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP, CPP,

The.C - case is important in GCC;.c is a C file, whereas.C is a C++ file (if you let the compiler decide what it is compiling that is).

Other suffixes are supported by GCC to signal specific processing; for example, a.ii file will be built as C++ but will not be pre-processed (intended for separately pre-processed code).

All recognized suffixes are listed at gcc.gnu.org.
