] End your loops with the cell pointer on the loop counter

At this point our program has added 5 to 2 leaving 7 in c0 and 0 in c1
|
|
but we cannot output this value to the terminal since it is not ASCII encoded.
|
|
|
|
To display the ASCII character "7" we must add 48 to the value 7.
|
|
We use a loop to compute 48 = 6 * 8.
|
|
|
|
++++ ++++ c1 = 8 and this will be our loop counter again

< . Print out c0 which has the value 55 which translates to "7"!
