Question

I have this as Main

int[] M ={ 10, 2, 30, 4, 50, 6, 7, 80 };  MyMath.Reverse(M);  for (int i = 0; i < M.Length; i++)      Console.WriteLine(M[i].ToString() + ', '); 

---

After I created the class MyMath I made the Reverse method

public int Reverse(Array M)  {      int len = M.Length;        for (int i = 0; i < len / 2; i++)         {            int temp = M[i]; M[i] = M[len - i - 1]; M[len - i - 1] = temp;         }             } 

but I’m sure it’s wrong because it’s not working 🙂 so do you have a different code to write in the reverse method?

note: I don’t want to use the built in Reverse in the Array class

---

yes guys when i used the built in reverse method i got this error

Process is terminated due to StackOverflowException.

thats after i wrote the method as

public static int Reverse(Array M) {     return Reverse(M); } 

So then I tried to create my own reverse method and there i got stuck

Working from your

public static int Reverse(Array M) {     return Reverse(M); } 

You have 2 problems.

1. Reverse(M) looks like the same function that you’re in, so you’re calling your new function, which calls itself, which calls itself, etc., resulting in the stack overflow. Change to return Array.Reverse(M);
2. Array.Reverse returns a void, so if you need to return an int (not sure what it’s supposed to be here) you’ll need to supply your own. Or change your Reverse function to be void.
