//NIM game between two players with 22 sticks #include

#include using namespace std;

int main ()

{

// declaring variables

const int total = 22; bool winner;

string play_again = "y";

int n, mtotal;

while(play_again == "y") {

winner = false;

mtotal = total;

do

{

//Turn for the player 1 to choose the stick (s)

if (mtotal > 0)

{

cout

cout

cin >> n;

if (n >= 1 && n

cout

mtotal -= n;

}

else

{

cout

} if (mtotal

{

winner = true;

cout
