c++ccompiler-specific

Write a program that will print "C" if compiled as an (ANSI) C program, and "C++" if compiled as a C++ program

Taken from http://www.ocf.berkeley.edu/~wwu/riddles/cs.shtml

It looks very compiler specific to me. Don't know where to look for?

Solution

  • Simple enough.

    #include <stdio.h>
int main(int argc, char ** argv) {
#ifdef __cplusplus
printf("C++\n");
#else
printf("C\n");
#endif
return 0;
}

    Or is there a requirement to do this without the official standard?
