title: C++ Multi Dimensional Array Problems - Entries printed more than once
body: <p>I have a 15x20 array, and I want to change the value of each entry, then cout them all.</p>
  
  <pre><code>char map[15][80];
  </code></pre>
  
  <p>Here is my code to cout all entries.</p>
  
  <pre><code>for (int a=0;a&lt;=15;a++) {
                for (int b=0;b&lt;=80;b++) {
                    map[a][b] = 'a';
                    cout &lt;&lt; map[a][b]; } }
  </code></pre>
  
  <p>The problem occurs if I place the alphabet into an array, it will print a certain letter more than once.</p>
