It's a pain having to study C, when your teacher spends most time saying:
"next year, when you study C++, you will discover that this, this and this
has got a much more friendly syntax..."

In this case, in C, you are comparing pointers.
whatever the content of S1 and S2 are, the result is false.

: In this case, in C, you are comparing pointers.
: whatever the content of S1 and S2 are, the result is false.

  But C has no string class, so it can't be C. That's C++ code. And it works.

Dear Warp,
I know that.
I think that my english is too poor, so I misunderstand sometimes the
questions :o(, and I shorten always my answers :o).
