What are the advantages of C++ programming compared to C programming?

c++ provides security to the data,c doesn't provide any
security to the data this is main advantage of c++ over than
c and c++ supports all concepts of c and it introduces
object oriented concepts like
objects,inheritance,polymorphism..etc.c++ programs are
useful for real-time purpose but c doesn't support.c++
introduces class concept.by using classes we can do
real-time projects.
c++ follows bottom-up approach but c follows top-down approach.
