title: how to take apart a number and multiply its digits?
body: <p>hi I'm using codeblocks and I'm kinda new, 
  I want to take apart a number and multiply its digits
  and if number is > 9 then once again I want to take apart the digits and multiply them,
  example: if I have the number 126 then the new number would be 1*2*6 = 12
  but 12 is > 9 then once again the new number is 1*2 = 2, 2 is not >9 then get out of the loop 
  thanks </p>
