title: help with byte array
body: <p>I have one byte array which has some raw data like 1aa23486b2..and so on.
  I want to represent each byte in the array as a decimal number. I then have to go through the decimal numbers and pick out the first x decimal to output to screen. </p>
  
  <p>if i use int byte [same size as input byte array] would that work? just declare and initialized it
  memset(byte,0,same size as input byte array];</p>
  
  <p>then just loop through and copy it over which could do the trick but then how do i choose x amount of digits? </p>
