trim heading and trailing space

[=?Utf-8?B?R2Vvcmdl?=]

Hello everyone,
I think in built-in C/C++ functions, there is no direct function call to
trim heading and trailing space characters, right? So, we have to implement
it manually by iterating the string to check character one by one.

Support not using MFC.
thanks in advance,
George

George,

You're posing in a .Net group, so if you're using String ^, there is a
Trim method already.

If you're using native C++ using std:string, you might want to have a
look at the Boost library facilities which I believe have trim
facilities
(http://www.boost.org/doc/html/string...html#id1638126)

MFC's CString has its own Trim method built-in.

Thanks Dave,
I think there is no built-in trim functions in even STL string. Right?

None that I'm aware of - hence the Boost suggestion. There's an
article on CodeProject too -

Hi Dave,
It is implemented by find_first_not_of and find_last_not_of of STL string,
no built-in functions.

Yes, that's what the CodeProject article uses.

Thanks Dave,
I think there is no built-in trim function and the method described in
CodeProject seems to be the best way.
