Is C++ fully compatible with C?

C++ is a subset of C as it is developed and takes most of its procedural constructs from the C language. Thus any C program will compile and run fine with the C++ compiler. However, C language does not support object-oriented features of C++ and hence it is not compatible with C++ programs.

  1. // C++ code:
  2. class C {
  3. // …
  4. virtual double f(int);
  5. };
  6. extern “C” double call_C_f(C* p, int i) // wrapper function.
  7. {
  8. return p->f(i);

How is C different from C++?
