如果语句在c ++，freaks out [英] If statement in c++, freaks out

问题描述

当我试图运行这个游戏，想要结束它通过键入slut或slut（瑞典语为'end'）它使一个新的播放器调用slut或荡妇 BUT 当我只有一个语句在while循环或If语句它都工作。
为了使它更清楚它工作时，我有（playerName！=Slut）但我想安全有（playerName！ （playerName！=slut），然后它不工作。

when I try to run this game and wants to end it by typing "slut" or "Slut" (Swedish for 'end') it makes a new player call "slut" or "Slut" BUT when I only have ONE statement in the while loops or If statements it's all working. To make it more clear It works when I have (playerName != "Slut") but I want for safty have (playerName != "Slut") || (playerName != "slut") and then it wont work.

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

int main（）{

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;
int diceRoll2 = 0;
string playerName;
string playerLost;
//Plants a seed
srand((int)time(0));
//Instructions
cout << "Nu spelar vi "Otur i tärning": " << endl;
cout << "Hur många tärningskast ska göras per spelare?" << endl;
cin >> dices;


//If "slut"/""Slut" is written, while stops
while ((playerName != "Slut") || (playerName != "slut")){
    cout << "Namnet på spelaren?";
    cin >> playerName;

    for (int i = 0; i < dices; i++){

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

            diceRoll1 = rand() % 6 + 1;
            diceRoll2 = rand() % 6 + 1;
            cout << diceRoll1 << " " << diceRoll2 << " = " << diceRoll1 + diceRoll2 << endl;

            diceSum = diceSum + diceRoll1 + diceRoll2;




        }
    }

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



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

            absoluteLowestSum = diceSum;
            playerLost = playerName;                    //Give us the name who lost

        }

        cout << "Summan: " << diceSum << endl;

        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;

}

推荐答案

您必须使用&&& ，而不是 || p>

You have to use && instead of ||.Its supposed to be

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

和

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

如果 s和而条件具有！= （ playerName！=Slut和 playerName！=slut）

in all the ifs and while conditions having != (playerName != "Slut" and playerName != "slut")
