Answer / guest

- Assigning int's to enum's.
- Assigning void pointers to other types of pointers.
- Function declaration foo() without parameters.
- Character constants are of type char in C++. They are of
type int in C.
- ALL functions MUST be prototyped in C++, which is not
required in C.
- In C++:
struct A { /* ... */ };
is equivalent to:
typedef struct A { /* ... */ } A;
in C.

Answer / achal ubbott

I just add 2 more points. C++ is a different language. Its
syntax matches to C accidentally.

1. C++ follows a name mangling algorithm for names of
functions. C does not.

2. C++ structures may have functions defined in them. Not
in C.

3. C++ follows more strict type checking.

Does c++ support multilevel and multiple inheritance?
