C program is standard C++ program?

[strutsng]

I want if "a C program is a standard C++ program, but not vice versa"
is a correct statement?

In a C++ program, we can use standard C libraries. However, we cannot
use C++ libraries inside C program.

Please advise. thanks!!

This has no effect on a C compiler, which by convention does not define
the __cplusplus macro, but signals to a C++ compiler that the
identifiers declared within are to be linked with a C object file.

<nit size=microscopic> No longer just convention. C99 6.10.8p5
specifies that a conforming C does not define __cplusplus . </>
