RPS Enumeration. Use the given enumerations to write a function Result getResult(Choice player1, Choice player2) .

Question

Use the given enumerations to write a function Result getResult(Choice player1, Choice player2) . It should determine the winner of a round of Rock, Paper, Scissors between two players (Rock beats Scissors, Scissors beats Paper and Paper beats Rock). Return WIN if player1 wins, LOSE if player1 loses or DRAW if there is no winner.

Code:

#include <iostream>

using namespace std;

//Lose =-1, Draw = 0, Win = 1

enum Result { LOSE = -1, DRAW, WIN };

enum Choice { ROCK, PAPER, SCISSORS };

//Do not modify anything on or above the line below this

//YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

int main()

{

Result result1 = getResult( ROCK, PAPER );

cout << result1 << endl;

Result result2 = getResult( ROCK, SCISSORS );

cout << result2 << endl;

Result result3 = getResult( ROCK, ROCK );

cout << result3 << endl;

Result result4 = getResult( PAPER, PAPER );

cout << result4 << endl;

Result result5 = getResult( PAPER, SCISSORS );

cout << result5 << endl;

Result result6 = getResult( PAPER, ROCK );

cout << result6 << endl;

Result result7 = getResult( SCISSORS, PAPER );

cout << result7 << endl;

Result result8 = getResult( SCISSORS, SCISSORS );

cout << result8 << endl;

Result result9 = getResult( SCISSORS, ROCK );

cout << result9 << endl;

}

Answer 1

Result getResult (Choice choicePlayer1, Choice choicePlayer2)

{

Result resultReturn;

switch (choicePlayer1)

{

case ROCK:

{

switch (choicePlayer2)

{

case ROCK:

{

resultReturn = DRAW;

break;

}

case PAPER:

{

resultReturn = LOSE;

break;

}

case SCISSORS:

{

resultReturn = WIN;

break;

}

} //nested switch player 2

break;

} //player 1 case ROCK

case PAPER:

{

switch (choicePlayer2)

{

case ROCK:

{

resultReturn = WIN;

break;

}

case PAPER:

{

resultReturn = DRAW;

break;

}

case SCISSORS:

{

resultReturn = LOSE;

break;

}

} //nested switch player 2

break;

} //Player 1 Case PAPER

case SCISSORS:

{

switch (choicePlayer2)

{

case ROCK:

{

resultReturn = LOSE;

break;

}

case PAPER:

{

resultReturn = WIN;

break;

}

case SCISSORS:

{

resultReturn = DRAW;

break;

}

} //nested switch player 2

break;

} //Player1 Case SCISSORS

} //switch player1 choice

return(resultReturn);
