Is this true ???
Isn't it natural to design them go together ?

If it is true can sombody explain why pop_back was excuded
as a member of basic_string ?

Speculation on the reverse.  Neither makes sense for string.
Push_back was included to allow back_inserter for use with
things like copy.  There is no like need for pop_back.

Is push_back, and pop_back member of basic_string ?

In The C++ Programming Language 3rd Edition,
Chapter 6 (p115) and Chapter 20 (p), there is an example
using push_back member of the string type
variable.

Is this Standard ?

Recent version of gcc and egcs doesnt support this
and can't find in CD2 either.

We are arguing in korean C++ newsgroup if this is
author's mistake, but unfortunately no person
who is arguing here purchaced the standard doucument
itself.

p.s.
    hope to see the special edition soon :-)

pop_back: No.

It's in the standard, in the synopsis in section 21.3/6. Due to an
oversight, it was left out of section 21.3.5.2. A defect report about
this omission was submitted back in 1997 and has been approved by the
library committee:

In the ISO 1998 C++ standard document was point out the following line

 void push_back(const charT); (page 385)

It is included only on Rogue Wave commercial libraries shipped with
Borland Builder and HP aC++.
It seems a print mistake.

Sorry for my bad english.
