title: Converting from a std::vector<int> to a char[] C++
body: <p>If I have an integer vector (std::vector) is there an easy way to convert everything in that vector to a char array(char[]) so (1,2,3) -> ('1','2','3')
  This is what I have tried, but it doesn't work:</p>
  
  <pre><code>std::vector&lt;int&gt; v;
  
  for(int i = 1; i  &lt; 10; i++){
      v.push_back(i);
  }
  
  char *a = &amp;v[0];
  </code></pre>
