Question

我正在尝试用c ++创建一个if else路径。我想要发生的是当我选择Anakin，然后是bool＆＃34; Anakin＆＃34; will = true，然后＆＃34;如果Anakin == true＆＃34;它将输出所需的代码，当我选择Heather时，然后＆＃34; Anakin == false＆＃34;它也会这样做。除非我选择＆＃34; Heather＆＃34;，否则输出代码就像我选择＆＃34; Anakin＆＃34;：

bool anakin;
char Name[25];
string choice;
int GameState;
int iRoomCounter[4] = { 0, 0, 0 }; // Used to determine if a room has been
visited.int main()
{
    cout << "" << endl;
    cout << "\t\t\tNimbus Town" << endl;
    cout << "What is your name?" << endl;
    cout << "Name: ";
    cin >> Name;
    cout << "All right " << Name << ", I will let you choose a friend that will be with" << endl;
    cout << "you along the way, okay? Great." << endl;
    cout << "Now choose your friend:" << endl;
    cout << "• Heather" << endl;
    cout << "• Anakin" << endl;
    cin >> choice;
    if (choice == "Heather") {
        anakin = false;
        cout << "You chose Heather, good choice!" << endl;
        GameState = START;
    }
    else if (choice == "Anakin") {
        anakin = true;
        cout << "Anakin, what a great choice!" << endl;
        GameState = START;
    }
    else {
        cout << "What?" << endl;
    }

    while (GameState != DEATH) {
        switch (GameState) {
        case START: {

            if (iRoomCounter[0] == 0) {
                if (anakin == true) {
                    cout << "\n'Hello, welcome to Nimbus town.'" << endl;
                    cout << "You jolted awake as an older, white-haired" << endl;
                    cout << "man greeted you. He was in a white tuxedo." << endl;
                    cout << "'My name is Kieran. What about you?'" << endl;
                    cout << "My name is " << Name << "." << endl;
                    cout << "Well " << Name << ", it's nice to meet you." << endl;
                    cout << "\nsomething doesn't feel right about him, but it's probably" << endl;
                    cout << "because I'm new here, you thought." << endl;
                    iRoomCounter[0] = 1;
                    if (anakin == false) {
                        cout << "Anakin is falseo." << endl;
                    }
                }
            }
        }
        }
    }
}

如果有人告诉我我应该做什么或提供建议/代码来帮助我，我会很感激。谢谢！

Answer 1

在C ++中，==用于测试相等性，而=用于分配值。在您的情况下，您尝试将值true分配给Anakin，但您使用的是==运算符。我怀疑将Anakin == false;和Anakin == true;行更改为Anakin = false;和Anakin = true;可能会解决您的问题。

Answer 2

现在您正在if语句中进行分配。在if语句中使用==，因为您要检查值是否匹配。分配新值时使用= 所以举个例子分配时

anakin = true;

和

if (anakin == false)

比较时

c ++如果其他文本程序没有进入我想要的路径
