C++ source code which must be preprocessed. Note that in .cxx, the
last two letters must both be literally x. Likewise, .C refers to a
literal capital C.
That means, gcc will consider a source file with name TESTING.C to be a
C++ source code. Thus trying to include / link with some special
libraries.
To compile your TESTING.C, use something like:
$ g++ -o TESTING TESTING.C
It 'll compile correctly.
Hope this helps.
