A: The simplest way is to use a stringstream:
#include
using namespace std;
string itos(int i) // convert int to string
{
stringstream s;
s << i;
return s.str();
}
int main()
int i = 127;
string ss = itos(i);
const char* p = ss.c_str();
cout << ss << " " << p << "\n";
Naturally, this technique works for converting any type that you can output using << to a string.
