Yes..Sorry C++

So, you want e.g.

int a = 57
to be converted into

char b = "57"
?

Oh no, Mr Bill!... that function is non-standard.

If we take the OP literally at his word, then technically only int values ranging from -128 to 127 can be converted to a char; if converting to an unsigned char, then values 0 through 255 can be used.

If the OP meant how to convert an int to an array of chars (aka a string), then the easiest and most portable C++ way is to use the std::stringstream.



int value = 12345;
std::stringstream ss;

ss << value;

std::cout << "As a string: " << ss.str() << std::endl;

Yep, I should have thought of that. I let a bad day at work get the better of me.

Sorry peeps. More specifically sorry Bong.Da.City

OTOH if you want it to be localizable to Hindu-Arabic numerals with a Duodecimal number base to be rendered right to left then you might need something a bit more flexible than stringstream :D

It's a good thing I completed my C++international numeric formatting library (http://code.google.com/p/speaknumber/downloads/list) for cases like this :D
