Working on long String in C++

[manishsharma1@gmail.com]

Hi,

I have one long String like this:

015EnvironmentD ata1........

I want to read first three character from it and convert them to
integer. This will be the length of the Name of the field and then
there is value. So if we take above example


015 means 15 - So we are going to read next 15 Character Starting with
E of "EnvironmentDat a" till "a".
Transfer it to come Variable say Field

Then I have to read the Value of this field which is followed by this
15 character long Field in the STring that is 1 in the above case.

I need help in Stripping of the String so that I can get all the
Fields and their values.

This has to be in C++. I am new at it. Please help.

Thanks in advance

Something like

std::string const blah("015Enviro nmentData1..... ...");
int n = -1;
std::ostringstr eam os(blah.substr( 0, 3));
os >n;
std::string Field = blah.substr(3, n);
os.str() = blah.substr(3 + n, 1);
int Value = -1;
os >Value;

This is untested and only intended to give an idea.

Hi Victor,

Thanks for reply.

This String is coming to the Parsing function in the form of pointer
to the string. Could you please advice something like the above
solution that will work with Pointer to String.

Thanks

std::string const blah(Pointer_To _String);

Everyting else is pretty much the same.

Hi Victor,

My code is Unicode and I have to use CstString. Please suggest some
solution related to that.

Thanks

Ask somewhere where CstString is topical. This is not the place.

Hello

I am afraid I don't know. I suppose you know the name of the library/
development environment you use? In that case it should be a matter of
minutes before googling e.g. google newsgroups should provide you with
the name of an appropriate newsgroup.

Does the German C++ standard define a type called CStdString, or are
they just more tolerant of off-topicality there?
