String Library - Page 2

He could have an old <iostream> library not able to support
strings with cout. Using a variable before it's been defined
produces a "undeclared variable" error not a type conflict.
As i said, Try using abc.c_str() wich turns it into a Character
array instead of a string wich should be compatible with
non-string supporting cout's.

1) How is that possible?
He stated in his first post that he is using VC++. So there is nothing wrong with his iostream lib version.

2) What is the use of declaring a string ONLY (and only ) to convert it to a char?
Might as well use a char straight away, you agree on this with me?

VC++ Doesn't mean VC++6, There are far older version wich
might not support strings.

You're overreacting on the "converting part", You just add .c_str
at the end, That's it. That doesn't stack up with the built in
functions and enhancements that come with the String Class.

The iostream library was always up to the standards as defined by ANSI standard in VC++.

The old lib (in pre-VC++ 6) was implemented correctly according the old ANSI standard and the new lib (VC++ 6) according the new ANSI standard.
In both cases, no changes were made to the functionality of "cout" vs strings.

I think mac messed up his libs by accident, and should re-install after completely un-installing

LOL

But there is another aspect. Omg lol.
He might use an incompatible iostream lib. For example, using a VC++ 5 iostream in a VC++ 6 environment!

But then again, it still means that his VC++ environment is messed up

You keep mentioning VC++ 6, Who says he has that?
Anyway, Let's wait till he tried the things mentioned out.

Not me.

Yes I am mentioning it, but not in a context like as he got it.
Whichever Microsoft version he has, it is interesting to know how the heck he could mess up iostream unless he "fooled around" with that library too.
That is all Trav.

The rest of my posts were scenarios, nothing more

String's weren't always standards (They still are barely in the
majority) so it isn't that suprising that iostream doesn't recognize
the String Class, Not his fault.

Wichever Microsoft version he has, it should work. If not, then his environment is messed up, for some reason.

The oldest VC++ dates back to DOS, String's weren't included
in the ANSI C++ standard, So has no reason for being included
back then, What if he has that one?
Anyway, Let's not jump to conclusion until we know the compiler.
