Re: [Dev-C++] Integer to std::string?

[Jason H. <jas...@bt...>]

I've been looking at it myself to, and AFAICT there isn't standard string
support for converting from int. None of the string members listed in "C++
The Complete Reference" do it.

I have found an alternative way of doing what sprintf does, which is more
C++ like, by using an Array Based Output Stream. e.g.

#include <stdio.h>
#include <stdlib.h>
#include <strstream>
#include <iostream>
#include <string>

int main(int argc, char *argv[])
{
    using namespace std;

    char str[80];
    ostrstream outs(str, sizeof(str));
    string mystring;

    outs << "An int " << 1024 << " or a float " << 1.234 << "." << ends;

    mystring = str;

    cout << mystring << endl;

    system("PAUSE");

    return 0;
}

I tested it just in case, and it seems to work OK, but is also a long winded
way of doing things.

I did not say that the idea of converting from numbers to string isn't
implemented in string, i said that i do not know it yet. :)
