Answer / dangling pointer
try this one
int *x=malloc(10);
it works in c but not in c++ reason is we will have to
explicitly cast in c++ to convert a void* to another type
to work.

Answer / dheeraj sharma
in c we can assign we can assign void pointer to any type of
pointor varible without typecasting.,but we cant do it in
C++,because C++ does not allow type mismatch.
same case with enum also.in C we can assign integer to enum
member directly,but in C++ we have to typecast integer first
with enum variable.

We can have variable names as class,new,operator in C but not in C++ as they are keywords in C++.

Answer / achal ubbott
One important difference between c and c++ is that c
compilers are loosely coupled. So it does not perform type
checking that much strictly and can allow some conversions
which otherwise most c++ compilers would not allow.

C++ will not allow declaration without initialization but C
will allow declaration without initialization.
And C++ and C both will not allow later initialization.

Theoratically it is being said that we cannot call main
recursively(main caling main) in c++, but practically it can
be done.
whereas in c, we can call main in main.

C++ retained all features of C programming in addition of
object oriented programming that use OBJECT and a CLASS so
there is nothing that happen in C but not in C++;

Answer / som
In C the const variables can be declared and can allocate
the value later.
For ex:
const int i;
i = 7;
This will work in c, but c++ will give compilation error.

How can you say that a template is better than a base class?
1. What does the following do: void afunction(int *x) { x=new int; *x=12; } int main() { int v=10; afunction(&v); cout<<v; } a) Outputs 12 b) Outputs 10 c) Outputs the address of v
