If you mean that it is usual to link shared libraries (such as .so or .dll),
that is true of both C and C++, but C++ requires more of them. 20 years
ago, C implementations which supported only static linking were more common
than now. Static linking will inflate the size of a C++ build much more
than a C build. Reasons for the differences are surely not topical on
c.l.c.
