title: Print address of string in Lua
body: <p>I want to print the starting address of string in Lua. So is there any way using which I can do that? for ex:-</p>
  
  <pre><code>x = "abc"
  </code></pre>
  
  <p>Now I want to print the address where abc is stored. So is there any way to do it? I will then pass this x to a C program and then try to print the address of x received to see that lua doesn't copy string but uses reference to the base address.</p>
  
  <p>So is there any method to do that?</p>
