u64 decimal to hex using C : <p>I have a titleID u64 array in which the first position consists of 16 decimal numbers.</p>

<pre><code>u64 titleID[] = {1266656072911941}
</code></pre>

<p>In this function:</p>

<pre><code>APT_PrepareToDoApplicationJump(0, 0x000_LL, 0);
</code></pre>

<p>How can I replace the <code>_</code> with the hex value of <code>titleID[0]</code>?
The <code>0x000_LL</code> parameter needs to have a u64 type as well.</p>

<p>Example using the provided titleID:</p>

<pre><code>APT_PrepareToDoApplicationJump(0, 0x0004800459474C45LL, 0);
</code></pre>
