有人可以告訴我這個嵌套循環中發生了什么嗎？

Question

有人請解釋下面的嵌套循環中發生了什么。 我在理解其工作方式時遇到了麻煩。

int numberOfTimesheets;
int centsPerHour = 0;
int hoursWorked;
total = 0;
numberOfTimesheets = stdin.nextInt();

for(int i = 1; i <= numberOfTimesheets; i++){
   hoursWorked = 0;
   centsPerHour = stdin.nextInt();
   for (int ii = 1; ii <= 5; ii++){
      hoursWorked = hoursWorked + stdin.nextInt();
   }
   total = total + (hoursWorked * centsPerHour);
}

Answer 1

嵌套for循環將出現5次，將5個用戶輸入加到變量hoursWorked 。 指向所有這一切可能是要計算用戶在該周中工作的小時數（每個星期中的每一天的每次迭代）。 然后通過將他的小時數乘以每小時的工資來獲得他的薪水，並將其加到total 。

這非常簡單，您可能唯一不了解的是：

hoursWorked = hoursWorked + stdin.nextInt();

它翻譯成這樣的東西：

new value of hoursWorked = old value of hoursWorked + userInput

它也可以寫成：

hoursWorked += stdin.nextInt();

Answer 2

這段代碼注釋了每一步的操作：

//go through each time sheet
for(int i = 1; i <= numberOfTimesheets; i++){
    hoursWorked = 0; // reset the number of hours worked (presumably for that week).
    centsPerHour = stdin.nextInt(); //get the wage of the current timesheet

    //go through each day for the current timesheet
    for (int ii = 1; ii <= 5; ii++){
        hoursWorked = hoursWorked + stdin.nextInt(); //add up the number of hours worked in that week
    }
    total = total + (hoursWorked * centsPerHour); //add the amount of money made this week to their current total (salary).
}
