The C code can be used with C++, although the following uses proper C++ iostreams:
<lang CPP>void number_reversal_game()
{
cout << "Number Reversal Game. Type a number to flip the first n numbers.";
cout << "You win by sorting the numbers in ascending order.";
cout << "Anything besides numbers are ignored.\n";
cout << "\t |1__2__3__4__5__6__7__8__9|\n";
int list[9] = {1,2,3,4,5,6,7,8,9};
do
{
shuffle_list(list,9);
} while(check_array(list, 9));
int tries=0;
unsigned int i;
int input;
while(!check_array(list, 9))
{
cout << "Round " << tries << ((tries<10) ? " : " : " : ");
for(i=0;i<9;i++)cout << list[i] << " ";
cout << " Gimme that number:";
while(1)
{
cin >> input;
if(input>1&&input<10)
break;
cout << "\nPlease enter a number between 2 and 9:";
}
tries++;
do_flip(list, 9, input);
}
cout << "Hurray! You solved it in %d moves!\n";
}</lang>
This uses the same helper functions as the C version.
=== Alternate version using the C++ standard library ===
This version uses the C++ standard library (note that none of the C helper functions are needed).

#include <ctime>

bool is_sorted(T (&array)[size])
{
return std::adjacent_find(array, array+size, std::greater<T>())
== array+size;
}
int main()
{
std::srand(std::time(0));
int list[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
do
{
std::random_shuffle(list, list+9);
} while (is_sorted(list));
int score = 0;
do
{
std::cout << "Current list: ";
std::copy(list, list+9, std::ostream_iterator<int>(std::cout, " "));
int rev;
while (true)
{
std::cout << "\nDigits to reverse? ";
std::cin >> rev;
if (rev > 1 && rev < 10)
break;
std::cout << "Please enter a value between 2 and 9.";
}
++score;
std::reverse(list, list + rev);
} while (!is_sorted(list));
std::cout << "Congratulations, you sorted the list.\n"
<< "You needed " << score << " reversals." << std::endl;
return 0;
