Question

当我尝试运行此游戏并希望通过键入＆＃34; slut＆＃34;来结束它时或者＆＃34; Slut＆＃34; （瑞典人为＆＃39;结束＆＃39;）它打了一个新的玩家电话＆＃34; slut＆＃34;或者＆＃34; Slut＆＃34; 但是当我在while循环或If语句中只有一个语句时，它都可以正常工作。为了使它更清晰当我有（playerName！=＆＃34; Slut＆＃34;）但我想要安全时有（playerName！=＆＃34; Slut＆＃34） ;）|| （playerName！=＆＃34; slut＆＃34;）然后它不会工作。

#include <cstdlib>

int main（）{

//Declaration
setlocale(LC_ALL, "Swedish");           //Swedish characters
int dices;
int diceSum = 0;
int absoluteLowestSum = 999999999;      //To get out the lowest sum I'm comparing to a big value
int diceRoll1 = 0;

            diceSum = diceSum + diceRoll1 + diceRoll2;




        }
    }

    if ((playerName != "Slut") || (playerName != "slut")){



        while (diceSum < absoluteLowestSum){        //Give us the lowest sum

            absoluteLowestSum = diceSum;

        diceSum = 0;                                //Puts the sum to 0 when a new player enters his/her name

    }

    if ((playerName == "Slut") || (playerName == "slut")){



        cout << playerLost << " hade mest otur och fick tärningssumman " << absoluteLowestSum << endl;

    }


}




return 0;

}

Answer 1

您必须使用&&而不是||。它应该是

if ((playerName != "Slut") && (playerName != "slut"))

和

while ((playerName != "Slut") && (playerName != "slut"))

在所有if和while条件下!=（playerName != "Slut"和playerName != "slut"）

如果在c ++中声明，那就吓坏了
