Unity3d Camera rotation not working

Question

Im trying to make my camera thats stuck to my player turn around it 45 degrees whenever i press Q or E. but for some reason i cant get it to work. im using C#.

using UnityEngine;
using System.Collections;
public class Camera : MonoBehaviour 
{
    int rotatespeed = 3;
    int rotationstart = 90;

    public GameObject player;

    private Vector3 offset;

    // Use this for initialization
    void Start()
    {
        offset = transform.position - player.transform.position;
    }     

    // Update is called once per frame
    void LateUpdate() {
            transform.position = player.transform.position + offset;
    }

    void Update()
    {
        if (Input.GetKey("q"))
        {
            Camera.main.transform.rotation = Quaternion.Euler(x + 45 , y, z);
        }
        if (Input.GetKey("e"))
        {
            Camera.main.transform.rotation = Quaternion.Euler(x - 45, y, z);
        }
    }
}

You should multiply when rotating

    if (Input.GetKey("q"))
    {
        Camera.main.transform.rotation *= Quaternion.Euler(45 , 0, 0);
    }
    if (Input.GetKey("e"))
    {
        Camera.main.transform.rotation *= Quaternion.Euler(-45, 0, 0);
    }

However this make it look up and down, if you want left and right use the following

    if (Input.GetKey("q"))
    {
        Camera.main.transform.rotation *= Quaternion.Euler(0, 45, 0);
    }
    if (Input.GetKey("e"))
    {
        Camera.main.transform.rotation *= Quaternion.Euler(0, -45, 0);
    }

Important side-note

Keep in mind that GetKey will return true while the user holds it down, which even on a very quick press will result in your camera seemingly spinning out of control due to it still being multiple frames. You most likely want to use GetKeyDown which will only return true once every time the user presses the key

alright, ive changed it a bit, ive also set it to javascript instead of C#. but now the camera is spinning, instead of it spinning around the character. Do you know how to make it spin around an fixed point?
