visual c++: convert int into string pointer

Question

how to convert integer into string pointer in visual c++?

Answer 1

This is how I did it in my homework since we were only allowed to use some predetermined libraries. I'm pretty sure it's not considered a "best practice" though ;)

string int2string(int integer) {
    string str;
    int division = integer;

    while (division > 0) {
        str = char('0' + (division % 10)) + str;
        division = division / 10;
    }

    return str;
}

Answer 2

search for atoi / itoa in your favorite documentation. Or try Boost (www.boost.org - library Conversion, lexical_cast).

Both ways are portable across different compilers.

Answer 3

Use stringstream

#include <sstream>
stringstream ss;
ss << i;
string   s = ss.str();

Answer 4

If you using CString, then you can use Format() method like this:

int val = 489;
CString s;
s.Format("%d", val);
