int to *char [C++]
Author
It's a pretty straitforward question, how do I convert a int to a char* or string (in C++) ?
I googled but amazingly I couldn't find anything relevant.
Your google-fu needs some work. "int to std::string C++" turns up hundreds of thousands of results.
Anyway, the solution is,
Or you can use C's itoa() function.
Anyway, the solution is,
#include <sstream>int i = 42;std::string s;std::stringstream out;out << i;s = out.str();Or you can use C's itoa() function.
#include <sstream>int main(){ int n = 42; std::string str; std::ostringstream ss; ss << n; str = ss.str(); return 0;}EDIT: Bah, too slow

Also note that "int to char*" is a bit smeary if you don't intend to take the value of an integer as an address of type pointer to char 0, but to convert it to a string.
0 this was actually my first thought, the solution would have involved type punning or so, leading you into the completely false direction. Luckily I scrolled down first ;)
