<div class="textblock"><p>Implementation of Linear <a href="https://www.geeksforgeeks.org/array-implementation-of-queue-simple/">Queue using array</a>. </p>
<p>The Linear <a class="el" href="../../dc/db5/struct_queue.html">Queue</a> is a data structure used for holding a sequence of values, which can be added to the end line (enqueue), removed from head of line (dequeue) and displayed. </p>
<h3><a class="anchor" id="autotoc_md28"></a>
Algorithm</h3>
<p>Values can be added by increasing the <code>rear</code> variable by 1 (which points to the end of the array), then assigning new value to <code>rear</code>'s element of the array.</p>
<p>Values can be removed by increasing the <code>front</code> variable by 1 (which points to the first of the array), so it cannot reached any more.</p>
