Accepted answer
#ifndef __cplusplus
If I remember correctly.

The identifier is __cplusplus
#ifdef __cplusplus
#error NO C++ PLEASE
#endif
0
#ifdef __cplusplus
with a few really ancient compilers (early 2 versions of cfront and a couple of ports) it 1 was c_pluplus, IIRC.
#ifdef __cplusplus
0
#ifdef __cplusplus
I think the file extension matters too, if 3 the C++ compiler is given a .c file it will 2 compile it as C code. i have nothing to 1 back this up though.
The identifier you are looking for is __cplusplus, which 1 can be used like this:
#ifdef __cplusplus
// Code being compiled as C++.
#endif
