title: How can I duplicate an array ? (with same size)
body: <p>I want to create a new array with the same size of "chaine" but only after the function</p>
  
  <pre><code> char chaine[Lenght];   //Lenght = 20
   function(chaine, sizeof(chaine));
  </code></pre>
  
  <p>When I called "function" the size of "chaine" is changing randomly.</p>
  
  <p>The new array "chaine2" also needs to be full of " * " characters.</p>
  
  <p>Let met try to explain with some printf :</p>
  
  <pre><code>     printf("chaine = %s\n", chaine);
  </code></pre>
  
  <p>will show on screen something like :   chaine = WORDS   (5 characters)</p>
  
  <p>And i want "chaine2" to be shown like this :  chaine2 = *****   (5 stars)</p>
  
  <p>I apologize for my english, thank you for reading</p>
