Hi, all:
I want to implement a function (using std::string and std::vector)
split a string contain special token into vector.
eg:
string = "alex delia john"
==>
vector[0] = "alex";
vector[1] = "delia";
vector[2] = "john";
I want use some stl algorithms library function,but I don't kown which
algorithms function is suitable.
Thanks !

You might try the new Boost String Algorithm library: http://www.boost.org/doc/html/string....html#id576776

I know boost string can split such string literal,but I want to
implement 'split' using stl.
Thanks your reply!

How about this -
string Str = "alex delia john";
std::istringstr eam iss( Str );
std::vector<str ing> vec( (std::istream_i terator<string> (iss)),
std::istream_it erator<string>( ) );

For homework, I guess?

You're welcome.

NO!
I just want to write a helper function for my workmates.

The best thing would be to give your workmates a boost using boost. Here you
get well-documented, tested code. Much better than anything you can expect
yourself to deliver.

> How about this - string Str = "alex delia john"; std::istringstr eam iss( Str ); std::vector<str ing> vec( (std::istream_i terator<string> (iss)), std::istream_it erator<string>( ) );
#include <string>
#include <vector>
#include <sstream>
int main(int, char**)
{
std::string Str = "alex de-lia jo-hn";
std::istringstr eam iss( Str ); // iss is a stream, that has the data
of Str
std::vector<std ::string> my_tokens(
(std::istream_i terator<std::st ring>(iss)),
std::istream_it erator<std::str ing>()
);
for (int i=0; i<my_tokens.siz e(); ++i)
{
printf("%s\n", my_tokens[i].c_str());
}
}
I don't get it quite. Especially this part:
(std::istream_i terator<std::st ring>(iss)),
std::istream_it erator<std::str ing>());
the first is an iterator to the begin of the string - what is the
second one? How does the spitting occour? Can I use different
seperators? Like ",-." ?
That's a terrific source code!

This comes up fairly frequently. You can either use stringstream
approach or something like the utility I posted here a few times. See
the link below: http://groups-beta.google.com/group/...9335f1c396d288
I would have reposted the code, but I'm stuck using google for a while
to post and it messes up code indentation.

I see this a lot, but I'll point out that many real projects don't
allow the programmers to drag in whatever third-party libraries they
feel like. It would take a long period of evaluation (as the Boost
stuff is non-standard and not provided by a vendor you can go to to
complain).

Hello one and all,
I'm developing an Asp.NET system to take a CSV file uploaded via the web,
parse it, and insert the values into an SQL database. My sticking point
comes when I try to split() the string returned by readline() on the file.
The following code snippet works for me:
tokens = "one,two,three,four".Split(",")
for each token in tokens
response.write("<td>"+token+"</td>")

Hi,
I am trying a basic opearation of splitting a multiline value to an
array of single lines(Actually making Address into AddressLine1,
AddressLine2).
I used Environment.NewLine in split, I could get only 1st line, but it
is not returning 2nd line.
here's code:
string address = null;
string ssep = Environment.NewLine;
char sep = ssep.ToCharArray();
