I need help for fixing a problem

Question

I created a program for the Mars rover challenge, and created a second version for random input.
The problem is in the second program, and i dont know where it actually is.
I dont want a complete solution for this, i want to fix it myself, but i need help by finding the problem and maybe an approach for fixing it.
The description for the problem itself is in the program in the space where i think this bug is created (line 29, where the commands are given a random value).
Thanks in advantage.

Answer 1

Hi Karl G. - Apologies for not seeing this sooner.

I've noticed a few issues in the code.

1. The variable `x` in the `for` loop on line 51 will be reset to `9` in the `for` loop on line 64 when the input contains "MOV". The reason is both `for` loops share the same variable `x`. The `for` loop on line 64 changes `x` to `4` and increments until `x < input.Length`.

When input is something like "MOV F 12", `x` will increment from `4` to `8` and then increment to `9` on the next loop on line 51.

Fix: Declare a different variable like `y` on line 64 and replace all references of `x` to `y` in the for loop block.

2. Line 123: When rockStash is 5, an Index Out of Range Exception will occur on Rock[rockStash, 1] because the array Rock was initialized as Rock[5, 3].

Fix: Modify line 115 to use the expression: (rockStash + 1 > 4)
instead of (rockStash + 1 > 5)

I've applied these fixes to this code in case you need something to reference:

Answer 2

Your code works well except for MOV and TRN

The problem is with
directionRandom[0,random.Next(1)]
directionRandom[1, random.Next(1)]

Write a test code on how to address the elements in nested array, and then you can know how to fix it. 😉

(by the way, i like the POS command and the RLS A option)
