Player 1, enter r for rock, p for paper, or s for scissors Player 2, enter r for rock, p for paper, or s for scissors Player 1 picked rock Player 2 picked scissors rock crushes scissors, player 1 wins

Player 1, enter r for rock, p for paper, or s for scissors Player 2, enter r forr rock, p for paper, or s for scissors Player 1 picked scissors Player 2 picked paper scissors cut paper, player 1 wins

Player 1 has 3 points, player 2 has 0 point, Player 1 is the winner!

}

还没有作loop, 不过在这里还有个问题

Expected Output

Player 1, enter r for rock, p for paper, or s for scissors Player 2, enter r for rock, p for paper, or s for scissors Player 1 picked rock Player 2 picked scissors rock crushes scissors, player 1 wins

要求 先cout Player 1, enter r for rock, p for paper, or s for scissors

然后 cin choice1,

之后 cout Player 2, enter r for rock, p for paper, or s for scissors

最后cin choice2,

这步应该写到哪里？新的function好点。。。还是写到GetChoice里面？
