Question

我有一项任务我在这里苦苦挣扎。这是一个基于循环的作业，对我来说有点模糊。作业如下：

询问学生姓名。
询问课程名称（不能小于0 - >如果是，请输入错误消息。）
询问他们提交了多少作业。
根据＃3，提出一些问题，例如可能获得的总积分和获得的积分，以生成进度报告。

除了＃4的开头部分之外，我并没有挣扎。我不完全确定如何创建一个为所提交的任务分配运行的循环？

这就是我到目前为止所做的，我主要是根据提交了多少作业来重复循环...我尝试过，我只是想不出来！我很有信心我可以做其余的事情:)）

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++;
}

这基本上是程序输出的内容：

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

Answer 1

删除;末尾的while(assign > loop)，否则您将在那里进行无限循环。

Answer 2

我会说你的作业检查的for循环更易读，可能会减少麻烦。由于您有assign作为分配数，因此您可以使用该变量来注释for循环中的每个分配。此外，您目前的解决方案似乎也有效。
