php - Trying to get property of non-object in laravel -

i have following code

in controller

  public function viewpost($id)         {              $viewpost= post::find($id);               return view('guest.viewpost', ['viewpost'=>$viewpost]);         } 

in view

  @foreach($viewpost $val)          <br>         post title=         <a href="viewpost/{{$val->id}}" >{{$val->post_title}}</a>       <br>         post content={{$val->post_content}}         <br>  <br>         featured image=<img src="{{$val->featured_image}}" height="150" width="150">       @endforeach 

but above code throw error trying property of non-object. tried following way

 $val['post_title']; 

the above code wont throw error nor displaying output.

if print in controller display output same in view if print give error

 print_r($viewpost); 

i using laravel 5.1. can 1 tell doing wrong ?

after suggestion of @coderomeos.i can able display data image not loading.

<img src="{{$val->featured_image}}" height="150" width="150">  <img src="uploads/penguin.jpg">
