Is there a way to print the corresponding source code (C++) as the program runs?

I know gdb, But I don't want to enter the interactive mode. I want the
program runs until it finishes without needing my intervention.

In interactive language such as R, both the source code along with the
output can be printed to stdout. This improves the productivity,
because I don't have to explicitly print anything to see where the
program run. If C++ has this capability, the programmer productive in
C++ can be improved.
