因为它是2名球员在输出中，它只询问玩家2按键，但对于玩家1则没有询问。但显示消息并执行下一步操作。对于每个玩家我给cin.get（），以便它要求用户按任意键，但此动作仅在玩家2处执行。谁能告诉我这个错误？

Answer 1

当您输入内容并输入cin时，似乎cin将'\n'退出，而您的下一个cin.get会收到输入密钥。要修复它，请更改部件：

cout<<"the position of player1 and player2 is 0 initially"<<endl;
while(p1_score<100 && p2_score<100)

成：

cout<<"the position of player1 and player2 is 0 initially"<<endl;
cin.get();
while(p1_score<100 && p2_score<100)

另一种方法：

以上方式可以很好地完成工作。但是以下代码更好。它忽略了您的额外'\n'：

cout<<"the position of player1 and player2 is 0 initially"<<endl;
cin.clear();
cin.ignore(INT_MAX, '\n');
while(p1_score<100 && p2_score<100)

请注意，对于INT_MAX，您需要额外的库：

#include <climits>

或者，您可以用大号替换INT_MAX，例如10000。
