Install ldd to find out?

If you compile it with g++, it will need the C++ runtime library, even if the
program source is plain C:
| anakin$ cat hello.c
| #include <stdio.h>
| #include <stdlib.h>
|
| int main(int argc, char *argv[])
| {
| printf("Hello, world! [C]\n");
| exit(0);
| }
|
| anakin$ gcc hello.c
| anakin$ ldd a.out
| libc.so.6 => /lib/tls/libc.so.6 (0x41019000)
| /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x41000000)
| anakin$ mv hello.c hello.C
| anakin$ g++ hello.C
| anakin$ ldd a.out
| libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x40016000)
| libm.so.6 => /lib/tls/libm.so.6 (0x41156000)
| libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x4131a000)
| libc.so.6 => /lib/tls/libc.so.6 (0x41019000)
| /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x41000000)
| anakin$

If it's C, why not compile it with the C compiler instead of the C++ compiler?

when I'm talking to journalists I just say "programmer" or something like that.
