我正在运行一个纸牌游戏，两个玩家轮流挑选纸牌，玩家向前走那么多格子。在这种情况下，一旦任一玩家达到 25 或更大的数字，他们就会点击 Home，游戏应该停止。
//This is the function that plays the entire game
void play(int size, int &player1, int &player2, int cardPile[], int board[]){
displayRules();
while(player1 < 25 || player2 < 25){
cout << "\nPlayer 1's turn!" << endl;
takeTurn(size, player1, cardPile, board, player2);
showState(player1, player2);
cout << "\nPlayer 2's turn!" << endl;
takeTurn(size, player2, cardPile, board, player1);
showState(player1, player2);
}
}
我的 while 循环在两个玩家都达到 25 后继续循环，即使我已将条件设置为在玩家 1 的值小于 25 或玩家 2 的值小于 25 时循环。

while 循环条件哪里出错了？
编辑:这是我运行的其中一项测试的一些输出。
Welcome to GoHome! The main objective of this game is to reach Home first.
The basic rules of the game are as follows:
-To begin the player with the shortest name goes first.
-Each player picks a card that has a number on it and the player must moves forward that many number of spaces.
-If a card says 'Lose A Turn', the player does nothing and theturn moves to the next player.
-If a card says 'Switch Places', that player is allowed to switch places with any player on the board.
-If a player lands on an obstacle, that player must move back that many number of spaces.
-If a player lands another obstacle while moving backwards, then it does not have to move backwards again.

最佳答案
好吧，您的条件是“当玩家 1 小于 25 或玩家 2 小于 25 时，执行循环中的操作”。但这绝对不是你想要的。简单地改变:
while(player1 < 25 || player2 < 25){
到
while(player1 < 25 && player2 < 25){
我认为会完成工作。
这与 De Morgan's laws 有关, 从逻辑上。
此外，请记住，要让程序在任一玩家达到 25 时终止，您必须在每一 回合之后询问，即在每次 takeTurn 调用之后。
关于c++ - 我的 While 循环不会在条件处停止，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46459643/
