Rock Paper Scissors game help!

tylrat93 (2)
I currently have an almost finished program of Rock Paper Scissors, sepereated into 4 functions, I can get the players choice and the computer choice to print out I just need it to print out who wins and i need it to ask how many games of RPS you want to play, odd of course, then output the winner of the Game much like tennis.

The functions playerChoice and compChoice don't return any anything. Also, assuming that totalOutcome stores the number of times the player has won, gameOutcome should also return 1 for win and 0 for loss. Then you can add the returned value to totalOutcome.

As for having a set number of rounds, you can ask the player for a value, check if it's odd using mod, and then have the code in a for loop. To check who won, you can use

1
2
3
 
if (totalOutcome > (numberOfRounds - 1) / 2) {
    // code
}


Hope this helps.
