You should use int main() instead of void main()

Answer 3

The simplest way is to use a stringstream:
#include<iostream> #include<string> #include<sstream> 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"; }
