Any convenient ways of converting ints to strings?

Are there any convenient ways of converting ints to strings?
Without having to do huge if ladders or alike.
Boost lexical_cast, or for a basic mockup of what it does:
template<typename R, typename T>R lexical_cast(const T& t) { R ret; std::stringstream st; if(!(st<<t) || !(st>>ret)) throw std::bad_cast(); return ret;}//usage:std::string s = lexical_cast<std::string>(10);
The way I do it:
inline std::string IntToString(int nNumber){char szBuff[32]; sprintf(szBuff,"%d",nNumber); return szBuff;}

Thanks, after reading the resource page I went for a similar approach than that of Evil Steves'. :)
I normally use itoa, but after seeing the way you do it Evil Steve, I think I'm going to change my ways ;-)
What are the params for it though?
Edit: Do you have a link that tells me how to use this fully? I've had a look on msdn, and it's confusing and not very helpful (doesn't give a list of possible params)

eh, I'm not sure what you're asking Tera, but the Evil's function is ready for usage.
ex.
int month = 10;
string tempmonth;
tempmonth = IntToString(month);

int month = 10;
string tempmonth;
tempmonth = IntToString(month);
Ok, maybe I didn't word that well.
What I wanted to know was what does the "%d" mean? And what other flags are there?

void int2string(int n, std::string &str){ do { int d = n % 10; n = n / 10; str += '0' + d; } while(n != 0);}That should do it.

%d - insert int
%f - insert float
%x - insert int in hex form
%s - insert string
there are some more but i cant remember them

%d reads a decimal integer
%i reads an integer
%c reads a char
%f reads a float
%s reads a string
%u reads an unsigned int
etc.
You should find the rest of the flags easily by searching for sprintf reference.
