c++ - 网球记分员

我愿意用C++编写网球得分管理员的代码来跟踪得分，但是当我运行该程序时会出现2个问题:

我无法使用while(cin!=“q”)

退出循环

函数不会初始化变量

#include<iostream>
#include<string>
using namespace std;

int points1=0, points2=0;
int set1=0, set2=0;
int games1=0, games2=0;
string in="";
void score(int point,int set,int game);
int main()
{

    do
    {
      cout<<"POINTS: "<<points1<<":"<<points2<<endl<<"SETS: "<<set1<<":"<<set2<<endl<<"GAMES: "<<games1<<":"<<games2<<endl;
      cout<<"Who scored - player 1 or player 2? (p1/p2) :  ";
      cin>>in;
      if(in=="p1")
      {
       void score(int points1,int set1,int games1);
      }
      else if(in=="p2")
      {
       void score(int points2,int set2,int games2);
      }
      else {cout<<endl<<"Error!"<<endl<<endl;}
      }
      while(cin!="q");



    system("pause");
        return 0;
   }

 void score(int& point,int& set,int& game){
  if(set<5)
  {
   switch(point)
   {
       case '30':
            point=point+10;
       case '40':
            set++;
            point=0;
       default:
            point=point+15;
      }
   }
   else game++;
}

最佳答案

您想要一个带有while的无限break循环，还要摆脱函数调用中的defs类型-类似于:

while (true) {
    cin >> in;
    if (in == "p1") {
        score(points1, set1, games1);
    }
    else if (in == "p2") {
        score(points2, set2, games2);
    }
    else if (in == "q") {
        break;
    } else {
        cout << endl << "Error!" << endl << endl;
    }
}
