title: How to access global variable when there is a local and global conflict
body: <p>Code : </p>
  
  <pre><code>int a = 33;
  int main()
  {
    int a = 40; // local variables always win when there is a conflict between local and global.
    // Here how can i access global variable 'a' having value '33'.
  }
  </code></pre>
  
  <p>If you ask : Why would someone want to do above thing? Why [a-zA-Z]* ?</p>
  
  <p>My answer would be : Just to know that 'it is possible to do so'.</p>
  
  <p>Thanks.</p>
