Print c with gcc and c++ with g++

Question

Can anybody tell how to write a program which when compiled with gcc prints c , and with g++ prints c++?

Answer 1

#ifdef __cplusplus
    printf("c++\n");
#else
    printf("c\n");
#endif

You may run into issues if your file extension isn't right.

Answer 2

Something like this:

#if __cplusplus
    printf("c++");
#else 
    printf("c");
#endif

Unless you're compiling with g++ -x c which it will still print C even though compiled with g++. That's a gotcha.
