我有一个任务，我在这里遇到了很多困难。这是一个基于循环的分配，这对我来说有点模糊。任务如下：

  1. 问学生姓名。
  2. 询问课程名称（不能小于 0 --> 如果是，错误信息。）
  3. 询问他们提交了多少作业。
  4. 根据#3，提出一些问题，例如可能的总分和获得的总分，以生成进度报告。

除了#4 的开头部分，我没有为任何事情苦苦挣扎。我不完全确定如何创建一个针对已提交的许多作业运行的循环？

这就是我到目前为止所拥有的，我主要是在根据提交的作业数量重复循环......我试过了，我就是想不通！我很有信心我能做剩下的:)

String studentName = " ";
String courseName = " ";
int assign = 0;
int loop = 0;
int totalScore = 0;
int scorethisAssign = 0;

System.out.println("Enter student name:");
studentName = input.next();
System.out.println("Enter course name:");
courseName = input.next();

System.out.println("How many assignments have you submitted:");
assign = input.nextInt();

while (assign <= 0) {
    System.out.println(" ");
    System.out.println("You must enter a number greater than 0 -- TRY AGAIN!");
    System.out.println("How many assignments have you submitted:");
    assign = input.nextInt();
}

while (assign > loop);
{
    System.out.println("How many points was assignment "loop + "worth:");
    scorethisAssign = input.nextInt();
    totalScore = scorethisAssign + totalScore;
    loop++;
}

这基本上是程序将输出到的内容：

Enter student name: Prince Harry
Enter course name: Intro to College Life

How many assignments have you submitted: 4

How many points was assignment 1 worth: 100
How many points did you score: 45

How many points was assignment 2 worth: 75
How many points did you score: 46

How many points was assignment 3 worth: 100
How many points did you score: 83

How many points was assignment 4 worth: 100
How many points did you score: 74


Progress Report for Prince Harry

删除;末尾的while(assign > loop)，否则你将在那里有一个无限循环。

我会说for你的分配检查循环更具可读性，并且可能会给你带来更少的麻烦。由于您有assign分配的数量，您可以使用该变量来注释for循环中的每个分配。此外，您当前的解决方案似乎也有效。

Java 'for' 语句
