所以我遇到的问题是：当满足胜利条件时，程序应该停止while循环并只显示获胜/失败/平局消息，而是允许游戏的X和O取得又转了一圈，我不知道为什么。任何帮助将不胜感激。

答案 0 :(得分：3)
我已经明白了......如果您要使用playerChar检查isMoveValid()，我会在每次X检查后更改O。X在检查胜利者之后进行简单的更改。这将给出正确的结果。
最初，当player1提供O位置时，您正在检查获胜行动以获得#include <cmath>
#include <cstdlib>
#include <iostream>
using namespace std;
void PizzaMenu();
void SizePrices();
int main()
{
double personal = 10.00;
double medium = 14.50;
double large = 19.00;
double xlarge = 23.50;
double FlavorChoice=0;
int SizeChoice;
int PizzaCountP=(cin >> PizzaCountP, PizzaCountP);
int PizzaCountM = (cin >> PizzaCountM, PizzaCountM);
int PizzaCountL = (cin >> PizzaCountL, PizzaCountL);
int PizzaCountXL = (cin >> PizzaCountXL, PizzaCountXL);
double orderTotal = (personal * PizzaCountP) + (medium * PizzaCountM) + (large * PizzaCountL) + (xlarge * PizzaCountXL);
cout << "Welcome to Joes pizza place!" << endl;
do{
PizzaMenu();
cout << "\nPlease chose a pizza from the menu(1-6): ";
cin >> FlavorChoice;
SizePrices();
cin >> SizeChoice;
if (SizeChoice > 0 && SizeChoice < 5)
{
switch (SizeChoice)
{
case 1:
cout << "How many personal pizzas? "; cin >> PizzaCountP;
break;
case 2:
cout << "How many medium pizzas?"; cin >> PizzaCountM;
break;
case 3:
cout << "How many large pizzas?"; cin >> PizzaCountL;
break;
case 4: cout << "How many extra large pizzas?"; cin >> PizzaCountXL;
break;
default: cout << "please enter a choice (1-4)"; cin >> SizeChoice;
break;
}
}
if (PizzaCountP > 0 || PizzaCountM > 0 || PizzaCountXL > 0 || PizzaCountL > 0)
{
printf("Your total is: %a", orderTotal);
}
} while (FlavorChoice != 6);
cout << "Thank you for visiting Joes place pizza! "<<endl;
}
void PizzaMenu()
{
cout << "\nSpecialty Pizza Menu" << endl;
cout << "\n1)Pizza 1" << endl << "\n2)Pizza 2" << endl << "\n3)Pizza 3" <<endl << "\n4)Pizza 4" << endl << "\n5)Pizza 5" << endl << "\n6)Pizza 6" << endl;
}
void SizePrices()
{
cout << "1) 10'' Personal" << "\t" << "- $10.00" << endl;
cout << "2) 14'' Medium" << "\t" << "- $14.50" << endl;
cout << "3) 16'' Large" << "\t" << "- $19.00" << endl;
cout << "4) 18'' Extra Large" << "\t" << "- $23.50" << endl;
cout << "Your choice (1-4)? ";
}
，而在以后的情况下，这种情况也会发生.. 这就是为什么＆## 39;得到错误。
