推荐答案

这甚至不应该编译，因为您已经两次声明了一些变量.

This shouldn''t even compile because you''ve declared some of the variables twice.

const int maximumLineNumber = 50;
const int pageLength = 20;
const int pricePerLicense = 1100;
const int packageOfLicenses = 10;

static void Main()
{
    int maximumLineNumber;
    int pageLength;
    int pricePerLicense;
    int packageOfLicenses;

删除您的const定义.它们是完全不必要的.

Delete your const definitions. They''re completely unnecessary.

只需更改这大部分并可以正常工作

Just change this much part and its working fine

int discount = 3500;
            int numberOfLicenses = 1;
            string val = "";
            for (lineNumber = 1; lineNumber <= maximumLineNumber; lineNumber++)
            {
                if (packageOfLicenses == (10 * numberOfLicenses))
                {

                    discount = 3500 * lineNumber;
                    quantityOfLicenses = packageOfLicenses * lineNumber; /* Assuming packageOfLicenses=10, we print price of 10 licenses on line 1, and 20 licenses on line 2, …*/
              totalForLicenses = quantityOfLicenses * pricePerLicense;
              if (lineNumber % 10 == 0)
              {
                val = val + "\n Line " + lineNumber + ": "
               + quantityOfLicenses + " Licenses " +
                "cost " + (totalForLicenses - discount);
              }

                }

                if ((lineNumber % pageLength) == 0) Console.ReadKey(); /* pause after every page printed */
            }


            Console.Write(val);
            Console.ReadKey();
        }
