How to convert an integer into a string

[silverburgh.meryl]

In my c++ code, I try to call "itoa"

#include <stdio.h>
#include <stdlib.h>

int index2
char buffer [4];
::itoa (index2,buffer,10);

but I get this compile error:

Context.cpp:2304: error: '::itoa' has not been declared

Can you please tell me how to fix that?

Thank you.

There is no such function as itoa in standard C++.

So is CreateWindowEx. As such, both are off-topic in this newsgroup.

I would like to do this on Linux, with G++. I think this question is
on-topic in this newsgroup.

Thanks for any help.

The question is on-topic and I posted a link to the FAQ which shows you
what you want. Here it is again.

The use of itoa was the off-topic bit.

int i = 1234;
std::stringstream ss;
ss << i;
std::string str(ss.str());

According to the Standard (17.4.3.1.2):

"Each name that begins with an underscore is reserved to the
implementation for use as a name in the global namespace."

Thus this name (_itoa) is reserved to the implementation and as such is
implementation specific, and off-topic.
