c++ - C++ 初学者 "while"程序

Question

我必须解决一个问题，我计算员工的薪水，他们在前 40 小时每小时获得 10 欧元，然后每增加一个小时他们获得 15 欧元。我已经解决了问题，但我的控制台无限循环地打印答案，我不知道我哪里错了。

int hours;
double salary;

int main()
{

    cout << "Enter amount of hours worked" << endl;
    cin >> hours;

    while (hours <= 40)
    {
        salary = hours * 10;
        cout << "Salary of the employee is: " << salary << endl;
    }

    while (hours > 40)
    {
        salary = (40 * 10) + (hours - 40) * 15;
        cout << "Salary of the employee is: " << salary << endl;
    }

    system("pause");
    return 0;
}

Answer 1

将 while 更改为 if。

while 中的条件将始终为 true，因为 hours 将始终小于 40，因为没有修改 hours 在 while 条件内，因此导致无限循环。

修改后的代码:

int hours;
double salary;

int main()
{

    cout << "Enter amount of hours worked" << endl;
    cin >> hours;

    if (hours <= 40)
    {
        salary = hours * 10;
        cout << "Salary of the employee is: " << salary << endl;
    }
    else //I have removed the condition because if hours is not less than 40,
        // it has to be greater than 40!
    {
        salary = (40 * 10) + (hours - 40) * 15;
        cout << "Salary of the employee is: " << salary << endl;
    }

    system("pause");
    return 0;
}

使用 while 循环的解决方案。

既然你一心想得到一个 while 循环解决方案，

代码:

int hours;
int counthour = 0;
double salary;

int main()
{

    cout << "Enter amount of hours worked" << endl;
    cin >> hours;

    while (counthour <= hours)
    {
        if(counthour <= 40)
            salary += 10;
        else
            salary += 15;
        counthour++;

    }
    cout << "Salary of the employee is: " << salary << endl;
    system("pause");
    return 0;
}
