using namespace std;
double playRPS (char a, char b);
int main() {
char letter;
char result = 0;
cout << "Welcome to COP3014 ROCK PAPER SCISSORS!\n\n";
cout << "Please select: " << endl
<< "Rock(r), Paper(p), or Scissors(s)? " << endl
<< "Or enter q to quit --> ";
cin >> letter;
if (letter == 'r' || letter == 'R' || letter == 'p' || letter == 'P' || letter == 's' || letter == 'S') {
playRPS(letter, result);
}
else {
cout << "Please enter r, p, or s" << endl;
}
return 0;
}
double playRPS (char x, char y) {
int choice1 = 0, choice2 = 0, choice3 = 0;
int user2 = rand() % 3 + 1;
if (( x == 'r' || x == 'R') && (user2 == '2')) {
cout << "The computer chose... PAPER!";
cout << "You chose ROCK!";
cout << "You LOSE!";
y = choice2;
