What is the difference between C and C++ struct?

1. C++ structs are like C++ class except the default access for struct is public v/s class is private
2. C struct can have integral data type only unlike C++ struct that can also have member functions
3. C struct cannot have access scope like public, private, protected, but C++ struct can.
4. struct A{ int i, int j } ; typedef A A1; typedef needed for C struct and not required for C++ , A can be directly accessed.
