i want generate a random num

<ol>
<li>Create an array containig all the candidate numbers, for instance <code>int value[]={1,2,3,4,5,6,7,8,9,10};</code>,
 initialize a variable that will keep  track of the sequence length, for instance <code>len=10;</code></li>
<li>make an loop for how many numbers you wish to extract, at each cycle</li><ol>
  <li>select an index number via <code>index = (int)( (double)rand() * len / RAND_MAX);</code></li>
  <li>keep the number corrensponding to the index, for instance <code>num = value[index];</code> that is you extracted one.</li>
  <li>swap the index selected with the one at the (the current) bottom of the array, i.e. <code>swap(value[index], value[len-1]);</code></li>
  <li>decrement <code>len</code>;</li>
</ol>
