Priority:Program Problem

[Lauren Zaj]

I am having trouble receiving the correct results with my rock-paper-scissors program. It is simply stating the player wins every time, and I cannot find the problem.

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <string>
#include <iomanip>
using namespace std;

const string name[4] = { " ", "rock", "paper", "scissors"};
const int size = 10;

void getPlayerChoice(int & choice){
cout <<"Pick 1 (rock), 2 (paper), 3 (scissors): ";
cin >> choice;
while ((choice < 1) || (choice > 3)){
cout << "Invalid choice, try again.\n";
cout <<"Pick 1 (rock), 2 (paper), 3 (scissors): ";
cin >> choice;
}
}


int getRoundResult(int computerChoice, int playerChoice){
if(computerChoice == playerChoice)
return 3;
else if( (playerChoice == 1 && computerChoice == 2) ||
(playerChoice == 2 && computerChoice == 3) ||
(playerChoice == 3 && computerChoice == 1) )
return 1;
else if ( (playerChoice == 2 && computerChoice == 1) ||
(playerChoice == 3 && computerChoice == 2) ||
(playerChoice == 1 && computerChoice == 3) )
return 2;
}


void showRoundResult(int computerChoice, int playerChoice, int roundResult){

if(roundResult == 3)
cout << " I chose " << name[computerChoice] << " too, so we tied.\n\n";
else if (roundResult == 1)
{cout << " I chose " << name[computerChoice] << ", so I win! "
<< name[computerChoice] << " beats " << name[playerChoice] << ".\n\n";}
else if (roundResult = 2)
{cout << "I chose " << name[computerChoice] << ", so you win! "
<< name[playerChoice] << " beats " << name[computerChoice] << ".\n\n";}
}

void showGameResults( const int results[] , const int size){
cout << " Game results\n";
cout << "--------------\n";
cout << left << setw(8) << "Round" << left << setw(10) << "Result" << endl;
cout << left << setw(8) << "-----" << left << setw(10) << "------" << endl;
for ( int lcv(0) ; lcv < 10; lcv++)
{cout << left << setw(8) << (lcv + 1);
if( results[lcv] == 3)
cout << left << setw(10) << "Tie" << endl;
else if ( results[lcv] == 1)
cout << left << setw(10) << "Computer win" << endl;
else
cout << left << setw(10) << "Player win" << endl;
}
}



int main(){

int roundResults[10];
int computerChoice,
playerChoice,
computerPoints = 0,
playerPoints = 0,
result,
round = 0;

srand(time (NULL));


cout << "Let's play Rock-Paper-Scissors!\n";
cout << "We will play 10 rounds.\n\n";

while( round < 10){
computerChoice = 1 + rand() % 3;
getPlayerChoice(playerChoice);
roundResults[round] = getRoundResult(computerChoice, playerChoice);
if(roundResults[round] = 2)
playerPoints++;
else if (roundResults[round] = 1)
computerPoints++;
result = roundResults[round];
showRoundResult(computerChoice,playerChoice, result);
round++;

}
showGameResults( roundResults , size);
cout << " Let's see how we did : \n";
cout << " You won " << playerPoints << " rounds and I won " << computerPoints << " rounds.\n";
cout << ( size - (computerPoints + playerPoints)) << " rounds were tied\n\n";
if(playerPoints > computerPoints){
cout << " Congratulations! You're the champ!\n\n";}
else if(playerPoints < computerPoints){
cout << " Sorry, you lost.\n\n";}
else
cout << " We Tied!\n\n";
