title: How to increment integer Array values?
body: <p>I am designing a problem in which I have to use an int array to add or subtract values. For example instead of changing 100 to 101 by adding 1, I want to do the same thing using the int array. It work like this:</p>
  
  <pre><code>int[] val = new int[3];
  
  val[0] = 1;
  val[1] = 0;
  val[2] = 0;
  
  val[2] += 1;
  </code></pre>
  
  <p>so, If I have to get a value of 101, I will add 1 to val[2].</p>
  
  <p>The only problem I have is finding a way to make int array work like how adding and subtracting from an ordinary integer data set works.</p>
  
  <p>Is this possible using a for loop or a while loop?
  Any help will be appreciated!</p>
