CS1002 expected

I have a script and I don't know what's wrong I'm kinda new and have seen it on youtube but it seems as it works for everyone else but not me this is the script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class water : MonoBehaviour
{
Transform floorlevel;
BoxCollider c;

void Start()
{
floorlevel = transform.GetChild(0)
c = GetComponent<BoxCollider>();

Adjustollider();
}

public void Adjustollider()
{

float waterSize = Vector3.Distance(transform.position, floorlevel.position);
float waterCenter = waterSize / 2;

c.size = new Vector3(c.size.x, waterSize + 0.25f, c.size.z);
c.center = new Vector3(0, -waterCenter, 0);
}


}

 

Please read this: https://forum.unity.com/threads/using-code-tags-properly.134625/

Define "works", what you expect and what you get instead? Read this too: http://plbm.com/?p=220

 

I have tried to do [c] but have not been working I don't see the problem nither did my friend the script it seems to work for others how tried it and a lot of people commented that it helped my no one seems to have my problem when I when others have the same problem they forgot to add ; but I haven't it just marks the c and says the error it's one of my first games I do w my friends and we do not find the problem we want the player to swim so any tips are Wellcome and have water to swim in

 

Apparently you have problems with basic understandings. I asked you to read what I showed you to actually format your code so it will be READABLE for humans. Not a bunch of text shoved onto the screen.
So I will do it for you, for the last time ever, because game development is not for the lazy. I know it sounds harsh, but it is true. We're not here to solve your problems, we're here to help you to solve your own problems.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class water : MonoBehaviour
6. {
7. Transform floorlevel;
8. BoxCollider c;
9.  
10. void Start()
11. {
12. floorlevel = transform.GetChild(0)
13. c = GetComponent<BoxCollider>();
14.  
15. Adjustollider();
16. }
17.  
18. public void Adjustollider()
19. {
20.  
21. float waterSize = Vector3.Distance(transform.position, floorlevel.position);
22. float waterCenter = waterSize / 2;
23.  
24. c.size = new Vector3(c.size.x, waterSize + 0.25f, c.size.z);
25. c.center = new Vector3(0, -waterCenter, 0);
26. }
27.  
28.  
29. }

Now, look at the 12th line in your code and tell me where do you see your semi-colon?
Also if you would have check the actual error message you're getting, it would tell you the actual line where the error occurs.
