How do i copy an entire file into a string

[owolablo]

I'm trying to make a subprogram,
Code:

void file2String(istream& in, string& theFile)
that can read an entire file into a string variable, including line
breaks and i have no idea what im doing. I'm using the GNU g++
compiler on Fedora 4 Linux Distribution.
Thanks in advance for the help

Use 'read' member of 'istream' and keep appending what you read to
the string, until an error or end-of-file.

We don't care.

You can also reserve enough space to read the entire file with one
dynamcic allocation (but keep std::string as out param and check the
return values):

Try this:

#include <iterator>

void file2string ( std::istream & in, std::string & str ) {
std::string dummy ( std::istreambuf_iterator<char>( in ),
(std::istreambuf_iterator<char>()) );
str.swap( dummy );
}

Best

in << ifstream(theFile).rdbuf();

To read it into a string make `in' be a stringstream.
