title: Programmatic way to get variable name in C?
body: <p>I am developing a tool to dump data from variables.
  I need to dump the variable name, and also the values.</p>
  
  <p>My solution: Store variable name as a string, and print the "variable name", followed by its value.</p>
  
  <p>Is there any programmatic way to know the variable name?</p>
