strcmp(a,b) is the C-way. (string1 == string2) give problems.
in the manual these functions relatively are hidden, that you have to 
install your own search-engine about it.

  What problems? If I do it the C++-way, there are no problems:

string s1 = "abc";
string s2 = "def";

if(s1 == s2) { ... }
else { ... }

sorry, i missunderstood your post. i thought you meant strcmp(a,b) is 
c++-way.
in my opinion the c-way is better, because coders then have less problems 
with type-casts.

  The c-way is awful.

  So you would prefer it also this way:

int a=1, b=2;

if(intcmp(a, b) == 0) { ... }

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).
