我认为程序的主要部分是完整的，但最后我需要输出：主题（subIn或sub1），等级（gradeIn或grade1）和点（pointsIn或points1）。
我需要用循环（分配点）来做这个，所以当我尝试运行程序时，我可以输入主题和等级，但我无法弄清楚如何输出所有信息。
当问题“再做一次？”时无论我输入“N”，它都不会输出任何东西。
（注意，我知道我在这段代码中没有输出任何信息，但是我试图将Console.WriteLine放在代码中并提供必要的输入，但无济于事。
代码：

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace caoAssignment

class Program
{
static void Main(string[] args)
{
// Delcaring variables //
string subIn, sub1, sub2, sub3, sub4, sub5, sub6;
string gradeIn, grade1, grade2, grade3, grade4, grade5, grade6;
int pointsIn, points1, points2, points3, points4, points5, points6;
int x;
string doAgain = "";
pointsIn = 0;
// Getting the user to input necessary information. 2 peices needed. //
do
{
x = 1;
while (x <= 6)
{
Console.WriteLine("Please enter a subject ");
subIn = Console.ReadLine();
Console.WriteLine("Please enter the grade you got in that subject (H1 - O8) ");
gradeIn = Console.ReadLine();
// Processing the grades in points //
if (string.Equals(gradeIn, "H1", StringComparison.OrdinalIgnoreCase))
{
pointsIn = 100;
}
else if (string.Equals(gradeIn, "H2", StringComparison.OrdinalIgnoreCase))
{
pointsIn = 88;
}
else if (string.Equals(gradeIn, "H3", StringComparison.OrdinalIgnoreCase))
{
pointsIn = 77;

因为你在学习我不想破坏乐趣。这是你正在做的伪代码。我已经为您想要仔细查看的部分添加了评论。
do
{
currentCount = 1;
while (currentCount <= maxCount)
{
subject = ReadSubject();
grade = ReadGrade();
points = GetPointsFor(grade);
if (IsValid(points)) //You currently have a bug here
{
StoreSubjectValues(currentCount, subject, grade, points);
currentCount++;
}
else
{
PrintError(subject, grade);
}
}
//This is what you want to add for the printout
for (currentCount = 1; currentCount <= maxCount; currentCount++)
{
PrintSubjectValues(subjectValuesFor[currentCount]);
}
userWantsToContinue = AskUserToContinue();
} while (userWantsToContinue);
关于循环，这是一个方便的指南：
do循环很好，如果你知道你想要至少循环一次，但在你开始之前不知道有多少循环。while循环是好的，如果你不知道你是否会循环，并且在你开始之前不知道何时结束。for循环是好的。当您知道需要存储许多相同类型值的实例时，请查看使用数组。在你的情况下科目，成绩和分数。在学习的后期阶段，您将使用集合和类/结构来存储这些，但在走这条路之前要熟悉数组。
祝你好运！
