C++：关于囚徒困境申请的建议

所以，基本上我正在为一个相当简单的囚犯困境游戏制作一个C++程序。

在我制作的这个变体中，囚犯B需要遵循囚犯A在上一轮中的做法。为了让它更容易，下面是我现在拥有的代码。

//////////////////////////////////
//+--------+---------+---------+//
//|Results | Silence | Confess |//<-prisonerB - opponent
//+--------+---------+---------+//
//|Silence |   3,3   |   0,5   |//
//+--------+---------+---------+//
//|Confess |   5,0   |   1,1   |//
//+--------+---------+---------+//
//////////////////////////////////
// ^prisonerA - us
#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
int numOfRounds;
char prisonerA; //us
char prisonerB; //opponent
int prisonerAYears;
int prisonerBYears;
int round; //num of round
int i; //counter

prisonerAYears=0;
prisonerBYears=0;
round=1;
cout<<"Enter the number of rounds you want to play: ";
cin>>numOfRounds;
while(numOfRounds>0)
{
numOfRounds=numOfRounds-1;
cout<<"Game "<<round++<<endl;
cout<<"What is your decision? Confess or stay Silent?(C/S) : ";
cin>>prisonerA;

while(round==1)
{
if ((prisonerA=='C') || (prisonerA=='c')) 
{
//prisonerB='C';
prisonerAYears=prisonerAYears+1;
prisonerBYears=prisonerBYears+1;
cout<<"Prisoner A (you) chose: Confess. Prisoner B (the opponent) chose: Confess."<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl;
}
else if((prisonerA=='S') || (prisonerA=='s'))
{
//prisonerB='C';
prisonerAYears=prisonerAYears+0;
prisonerBYears=prisonerBYears+5;
cout<<"Prisoner A (you) chose: Silence. Prisoner B (the opponent) chose: Silence."<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl;
}
}

}
cout<<"The rounds have come to an end."<<endl<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl<<endl;
if(prisonerAYears>prisonerBYears)
{
cout<<"You have to stay in prison longer. You lose."<<endl;
}
if(prisonerAYears<prisonerBYears)
{
cout<<"The opponent has to stay in prison longer. You win."<<endl;
}
if(prisonerAYears==prisonerBYears)
{
cout<<"You both are staying in prison for the same amount of time. Its a tie."<<endl;
}
return 0;
}

我还做了另外两个变化，对手总是坦白或保持沉默。这是对手保持沉默的地方。

#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
int numOfRounds;
char prisonerA; 
char prisonerB; 
int prisonerAYears;
int prisonerBYears;
int round; //broj runde
prisonerAYears=0;
prisonerBYears=0;
round=1;
cout<<endl;
cout<<"Enter the number of rounds you want to play: ";
cin>>numOfRounds;
cout<<endl;
while(numOfRounds>0)
{
numOfRounds=numOfRounds-1;
cout<<endl;
cout<<"Game "<<round++<<endl;
cout<<endl;
cout<<"What is your decision? Confess or stay Silent?(C/S) : ";
cin>>prisonerA;
cout<<endl;
if ((prisonerA=='C') || (prisonerA=='c')) 
{
prisonerB='S';
prisonerAYears=prisonerAYears+5;
prisonerBYears=prisonerBYears+0;
cout<<"Prisoner A (you) chose: Confess. Prisoner B (the opponent) chose: Confess."<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl;
}
else if((prisonerA=='S') || (prisonerA=='s'))
{
prisonerB='S';
prisonerAYears=prisonerAYears+3;
prisonerBYears=prisonerBYears+3;
cout<<"Prisoner A (you) chose: Silence. Prisoner B (the opponent) chose: Confess."<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl;
}
}
cout<<endl;
cout<<"The rounds have come to an end."<<endl<<endl;
cout<<"Prisoner A (you) is currently in for: "<<prisonerAYears<<" years."<<endl;
cout<<"Prisoner B (the opponent) is currently in for: "<<prisonerBYears<<" years."<<endl<<endl;
if(prisonerAYears>prisonerBYears)
{
cout<<"You have to stay in prison longer. You lose."<<endl;
}
if(prisonerAYears<prisonerBYears)
{
cout<<"The opponent has to stay in prison longer. You win."<<endl;
}
if(prisonerAYears==prisonerBYears)
{
cout<<"You both are staying in prison for the same amount of time. Its a tie."<<endl;
}
return 0;
}

这些都很容易。现在我被困在这里，因为我不知道如何提及囚犯A(或者我想，我)在上一轮中选择了什么。

在我定义的代码中，在第一轮比赛中，对手选择坦白。

如果有人能给我一个主意，告诉我如何领会我在上一轮比赛中所说的话，让对手从那时起遵循我的做法，我将不胜感激。

如果我没有解释清楚，请询问，以便我尝试进一步解释。
