当输入1到7之间的值时,程序应检查条件,如果值为1到7,并且输入的数字数组中的值不是0,但该程序的问题是,如果值[0]或其他数组为0,程序没有循环它继续运行

    do
            {
              cout << "Player 1\n";
              cout << "Please choose your location (1 to 7) => ";
              cin >> h1in ; // player 1 enters a value
              cin.clear();// used to clear the value if a str value is entered
              cin.ignore(1000,'\n');// used to clear the value if a str value is entered
              if ((h1in<1)||(h1in>7))
              {
                  cout << "You entered the wrong input \n\n";
              }
              if(house[h1in-1]==0)
              {
                  cout<<"jde";
              }

            } while((house[h1in-1]!=0)&(h1in<1)||(h1in>7));
if (h1in==1)
         {

答案 0 :(得分:2)

&是按位and。它在操作数的每个位上预先形成二进制and。您需要&&运算符,它是逻辑and

您还应该添加一些括号来制作最后一行:

while( (house[h1in-1]!=0) && ((h1in<1)||(h1in>7)));
