How to calculate the sum of 2 numbers with BrainFuck

Question

I\'m trying to write a program with BrainFuck that can read two numbers up to 9, calculate the sum of them and then print the result out, e.g. 3 & 5 give the result 8 .

Answer 1

That is what I know

,                           ;read character and store it in p1
------------------------------------------------   ;return ascii to Dec
<                           ;move pointer to p2 (second byte)
,                           ;read character and store it in p2
------------------------------------------------ ;return ascii to Dec
[                           ; enter loop
-                           ; decrement p2
>                           ; move to p1
+                           ; increment p1
<                           ; move to p2
]                           ; we exit the loop when the last cell is empty
>                           ;go back to p1
++++++++++++++++++++++++++++++++++++++++++++++++     ;return Dec to ascii
.                           ;print p1

input:

12

output:

3

You should use numbers under 10 and that result under 10
