string tmp;
int number;

cout << "Enter the number system to convert from (2..36): ";
cin >> ns_from;

cout << "Enter the number to convert: ";
cin >> tmp;

cout << "Enter the number system to covert to: ";
cin >> ns_to;
cout << endl;

number = strtol(tmp.c_str(), NULL, ns_from);
_itoa(number, buffer, ns_to);
cout << "The number converted: " << buffer << endl;
