用类，理解起来相对比较容易。

#include <iostream>using namespace std;class B{public:int num;B():num(0){}void display(){cout<<"B";}};class C{public:int num;C():num(0){}void display(){cout<<"C";}};class J{public:int num;J():num(0){}void display(){cout<<"J";}};class NumCount{public:int win;int tie;int lose;B b;C c;J j;NumCount():win(0),tie(0),lose(0){}void display(){cout<<win<<' '<<tie<<' '<<lose<<endl;}void winrecord(char a){if(a == 'B')++b.num;else if ( a == 'C')++c.num;else if ( a == 'J')++j.num;}void windisplay(){if( b.num >= c.num && b.num >= j.num){b.display();}else if ( c.num >= b.num && c.num >= j.num){c.display();}else if ( j.num >= c.num && j.num >= c.num){j.display();}}};bool comp(char a,char b){if( a == 'B'){if( b == 'C')return 1;}else if (a == 'C'){if ( b == 'J')return 1;}else if( a == 'J'){if ( b == 'B')return 1;}return 0;}int main(){int n;cin >> n;NumCount J,Y; char j,y;for (int i=0;i<n;++i){cin >> j >> y;if( j == y ){++J.tie;++Y.tie;}else{if( comp(j,y) ){++J.win;++Y.lose;J.winrecord(j);}else{++Y.win;++J.lose;Y.winrecord(y);}}}J.display();Y.display();J.windisplay();cout<<' ';Y.windisplay();return 0;}
