我该如何解决这个请指导 [英] How can I solve this please guide

问题描述

当我运行此代码时，它会在线路上给出错误，我在控制台的数组输入大小期间加下划线输入任意大小的



我是什么尝试过：

when ever i run this code it gives error on line which i underline during enter size of array at console enter any size of a

What I have tried:

{

          int a,b,c;
          double sum = 0,mul = 0, fx=0;

          Console.Write("Enter The size of Array :");
          a = int.Parse(Console.ReadLine());
          int[] array1 = new int[a];
          Console.WriteLine("Enter the Initial Value of Array Between  [-600, 600] : ");
          b = int.Parse(Console.ReadLine());
          c = b + a;
          for (int i = b; i < c; i++)
          {
              sum = sum + ((array1[i] * array1[i]) / 4000);
             mul = mul + Math.Cos(array1[i] / Math.Sqrt(i)) + 1;
              fx = sum - mul;
          }
          Console.WriteLine($"GRIEWANK FUNCTION  Output: {fx} ");
          Console.ReadLine();
      }

推荐答案

GRIEWANK FUNCTION输出：{fx}）;
Console.ReadLine（）;
}

"GRIEWANK FUNCTION Output: {fx} "); Console.ReadLine(); }

for (int i = b; i < c; i++)

你的循环需要从0变为a。 0-> a始终是数组的大小。 b和c是随机数，几乎肯定不在你的数组中。

Your loop needs to go from 0 to a. 0->a is always the size of your array. b and c are random numbers which almost certainly are not within your array.

什么时候我运行这个代码，它给出了我的下划线错误

when ever i run this code it gives error on line which i underline

您的代码没有按照您的预期行事，或者您不明白为什么！



有一个几乎通用的解决方案：一步一步地在调试器上运行你的代码，检查变量。

调试器在这里向你展示你的代码正在做什么和你的任务是与它应该做的比较。

调试器中没有魔法，它不知道你的代码应该做什么，它没有找到bug，它只是帮助你通过向您展示正在发生的事情。当代码没有达到预期的效果时，你就接近了一个错误。

要查看你的代码在做什么：只需设置断点并查看代码是否正常运行，调试器允许你执行第1行第1行，并在执行时检查变量。

这里的调试器只显示你的代码正在做什么，你的任务是与它应该做什么进行比较。

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
