title: Declaring std::map constants
body: <p>How to declare std map constants i.e.,</p>
  
  <pre><code>int a[10] = { 1, 2, 3 ,4 };
  std::map &lt;int, int&gt; MapType[5] = { };
  int main()
  {
  }
  </code></pre>
  
  <p>In the about snippet it is possible to give values 1,2,3,4 to integer array <strong>a</strong>, similarly how to declare some constant <strong>MapType</strong> values instead of adding values inside main() function.</p>
