Question

Possible Duplicates:
Is this a legitimate C++ code?
“C subset of C++” -> Where not ? examples ?

Could anybody come up with a piece of code that compiles with gcc or any other C compiler, and doesn’t compile g++ or any other C++ compiler?

UPDATE:
I don’t mean just keywords

UPDATE2:
Thank you All for answers. Apparently moderators were less enthusiastic than I was about subtle differences between C and C++.

UPDATE3:
to moderators: could you merge it with my previous question on the topic, as you suggested? It makes perfect sense to keep these two question together.

Answer 1

#include <stdlib.h>

int main()
{
    char* s = malloc(128);
    return 0;
}

This will compile with gcc, but not with g++. C++ requires an explicit cast from void* here, whereas C does not.
