title: Scenario where Union is better choice over Structure in C
body: <p>I'm looking for an scenario where using Union is a better option than Structure in C? </p>
  
  <p><strong>I'm not looking for the difference between the two</strong>. I'm aware of the Structure and Union concepts in C, and the difference.</p>
  
  <p>And I looked the question <a href="https://stackoverflow.com/questions/346536/difference-between-a-structure-and-a-union-in-c">Difference between a Structure and a Union in C</a>, which is no way the possible duplicate.</p>
