while循环条件比较字符串的问题

Question

我正在尝试使以下代码正常工作。我希望它是这样的，如果输入的人名不是“x”，我希望它跳过循环并结束。如果没有，我希望它循环。我认为条件如下所示：

void printProfile()
{
        //make a "cookie" or OBJECT
    HealthProfile user;
    //get name, age, weight, height info
    string personName = " ";
    int yrs;
    double weight, feetHeight, inchesHeight;

    //while the input isn't an x, keep going. if x is inputted, skip the while loop
    while(personName != "x")
    {
        //prompt name
        cout << "Enter name or X to quit: ";
        getline(cin, personName);
        //prompt age
        cout << "Your age: ";
        cin >> yrs;
        //prompt weight
        cout << "Your weight: ";
        cin >> weight;
        //prompt height feet
        cout << "Your height - feet: ";
        cin >> feetHeight;
        //prompt height inches
        cout << "Your height - inches: ";
        cin >> inchesHeight;

        user.setName(personName);
        user.setAge(yrs);
        user.setWeight(weight);
        user.setHeight(feetHeight, inchesHeight);

        cout << "Health Profile for " << user.getName() << endl;
        cout << fixed << setprecision(1) << "BMI: " << user.getBMI() << endl;
        cout << "BMI Category: " << user.getCategory() << endl;
        cout << "Max heart rate: " << user.getMaxHR() << endl;
    }
}

但它实际上在最后一次输入“x”时运行整个循环，然后结束程序。我该怎么做才能让输入 x 退出程序？

将循环条件更改为

while(true)

得到名字后，添加一个检查：

if((personName == "x")
    break;
