+
+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

+Finally print a newline:
