[brightoceanlight]

I have an integer. I need to return it as a string.

What is the best way to do this?

Using 'ostringstream', probably. Read the FAQ.

one way is

int i;
string s = boost::lexical_cast<string>(i);

#include<iostream>
#include<sstream>
using namespace ::std;
//-----------------------------------------------------
int main(int argc,char*argv[])
{
stringstream stream;
string str;
int i=911;
stream<<i;
str="int: ";
str+=stream.str();
str+=" inside string ;-)";
cout<<str<<endl;
return 0;
}

What is the best way to do this?

What is "the best way" ? ;-)

string s = boost::lexical_cast<string>(i);

Boost is not part of the C++ language at this time.

Of course! Boost is a library and C++ language is a language...

something they really forgot when writing std::string is the
printf-function:

#include <superstring>
int main()
{
int integer = 42;
std::superstring str;
str.printf("%d", integer);
}

And a good thing too:

#include <superstring>
int main()
{
double integer = 42;
std::superstring str;
str.printf("%d", integer);
}

Well, this NG is for discussion of the C++ *language*, not this or that
library that might be available for C++ (except for the Standard Library).
