i am having trouble with the fuctions: string getComputerChoice(string);string getPlayerChoice(string);
bool isTie(string, string);
bool isPlayerWinner(string, string);
heres my code:

int main()
{
char selection;
string computerchoice;
string playerchoice;
do
{
cout << "ROCK PAPER SCISSORS MENU ";

cin >> selection;
if(selection == 'p')
{
getComputerChoice(computerchoice);
getPlayerChoice(playerchoice);
//here its not displaying what i and the computer chosed.
cout << "You choose: " << playerchoice << " ";

Explanation / Answer
Here ya go. You were trying to assign the string using ==, but in order to ASSIGN a value, you have to use a single = Also, your functions weren't changing the actual value of the string, you have to pass it by reference in order to change the value of the original object. It displays now, but your game still has bugs that need to be fixed, such as figuring out who actually won, but I'll leave that up to you! :) #include #include #include #include #include using namespace std; void getComputerChoice(string&); void getPlayerChoice(string&); bool isTie(string, string); bool isPlayerWinner(string, string); int main() { char selection; string computerchoice; string playerchoice; do { coutRelated Questions
