title: declaration problem in .Net?
body: <p>Declare a Nullable variable</p>
  
  <p>e.g int? a = null; - This is true that a is having null value by default</p>
  
  <p>declare another variable</p>
  
  <pre><code>int b;
  b=a; // cannot convert from int? to int error
  </code></pre>
  
  <p>Main Point :-
  if a is not having value than null to be passed to b</p>
  
  <p>Point :- How you can get null value in b, do not convert int b to int? b - except this</p>
  
  <p>I need this solution ...anyone can help</p>
  
  <p>Is there any solution</p>
