title: Declaring a value for an int as unchangeable
body: <p>Hey I want to have something like that</p>
  
  <pre><code>int a=0;
  a=5(be unchangeable);
  a=3;
  Console.WriteLine(a);//which will print 5 and not 3
  </code></pre>
  
  <p>so basically make declare the variable a number and have it be final and unchangeable, I tried looking around but I only found things that work as the int is declared and not as a new value for it is declared.</p>
