title: Converting to uppercase in C++
body: <p>Let's say you have:</p>
  
  <pre><code>const char * something = "m";
  </code></pre>
  
  <p>How would one make this uppercase, using toupper (or something else, if applicable)?</p>
  
  <p>I want to use a <code>char *</code> instead of a <code>string</code> (I can use a string, but then I have to use <code>str.c_str()</code>).</p>
  
  <p>So, how can I make <code>char * something = "m";</code> contain <code>"M"</code>?</p>
