title: What is the default value of an uninitialized boolean array, in C?
body: <p>I have something like,</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;stdbool.h&gt;
  
  int main()
  {
      int t,answer;
      bool count;
      long long int L;
      scanf("%d",&amp;t);
      while(t&gt;0)
      {
          answer = 0;
          scanf(" %lld",&amp;L);
          bool count[L];
    //  .....restofthecode. NDA Constraint.
  </code></pre>
  
  <p>What would be the default value of all the elements of <code>arr[x]</code>?
  Is it <code>false</code> <strong>always</strong>? Or <code>true</code>? Or any random value?</p>
