使用C#进行先到先得(FCFS)CPU调度时出错

Question

有人能检查并修复我的代码吗？我面临以下错误：main.cs(80,10(：错误CS1525：意外符号=', expecting，'main.cs(80,25(：错误CS1525：意外符号)', expecting；'或}' main.cs(89,10): error CS1525: Unexpected symbol='，应为,' main.cs(89,25): error CS1525: Unexpected symbol('，应为;' or｝'main.cs(96.3(：错误CS1525：意外的符号"char"编译失败：5个错误，0个警告编译器退出状态1

我的代码：

只是想添加用户输入，比如进程数量和突发时间。

Answer 1

正如您已经注意到的，您缺少for关键字。此外，Console.ReadLine( )返回string而不是char。

应为：

string run = Console.ReadLine( );

或

var run = Console.ReadLine( );

虽然我认为你想阅读一个特定的密钥，所以试试：

var run = Console.ReadKey( );
while ( run.Key == ConsoleKey.Y );

我还注意到，在do while循环条件中使用的是赋值运算符=，而不是比较运算符==。

Answer 2

我忘记在循环中添加for关键字。
