title: What is the size (in bytes) of String comparing with char?
body: <p>I'm facing the memory enough in arduino, so I decided that i need to change variable types. Thinking about it, I would like to know the size in bytes of <em>String</em> comparing with <em>char</em> (1byte).</p>
  
  <p>I know that <em>String</em> is an object and <em>char</em> is a variable type.</p>
