有人可以告诉我这个嵌套循环中发生了什么吗？

Question

有人请解释下面的嵌套循环中发生了什么。 我在理解其工作方式时遇到了麻烦。

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循环将出现5次，将5个用户输入加到变量hoursWorked 。 指向所有这一切可能是要计算用户在该周中工作的小时数（每个星期中的每一天的每次迭代）。 然后通过将他的小时数乘以每小时的工资来获得他的薪水，并将其加到total 。

这非常简单，您可能唯一不了解的是：

hoursWorked = hoursWorked + stdin.nextInt();

它翻译成这样的东西：

new value of hoursWorked = old value of hoursWorked + userInput

它也可以写成：

hoursWorked += stdin.nextInt();

Answer 2

这段代码注释了每一步的操作：

//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).
}
