++ Cell c0 = 2
> +++++ Cell c1 = 5
[ Start your loops with your cell pointer on the loop counter (c1 in our case)
< + Add 1 to c0
> - Subtract 1 from c1
] 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
[
< +++ +++ Add 6 to c0
> - Subtract 1 from c1
]
< . Print out c0 which has the value 55 which translates to "7"!

[ This program prints "Hello World!" and a newline to the screen, its
length is 106 active command characters. [It is not the shortest.]
This loop is an "initial comment loop", a simple way of adding a comment
to a BF program such that you don't have to worry about any command
characters. Any ".", ",", "+", "-", "<" and ">" characters are simply
ignored, the "[" and "]" characters just have to be balanced. This
loop and the commands it contains are ignored because the current cell
defaults to a value of 0; the 0 value causes this loop to be skipped.

[<] Move back to the first zero cell you find; this will
be Cell #1 which was cleared by the previous loop
<- Decrement the loop Counter in Cell #0
] Loop until Cell #0 is zero; number of iterations is 8
The result of this is:
Cell no : 0 1 2 3 4 5 6
Contents: 0 0 72 104 88 32 8
Pointer : ^
>>. Cell #2 has value 72 which is 'H'
>---. Subtract 3 from Cell #3 to get 101 which is 'e'
+++++++..+++. Likewise for 'llo' from Cell #3
>>. Cell #5 is 32 for the space
<-. Subtract 1 from Cell #4 for 87 to give a 'W'
<. Cell #3 was set to 'o' from the end of 'Hello'
+++.------.--------. Cell #3 for 'rl' and 'd'
>>+. Add 1 to Cell #5 gives us an exclamation point
>++. And finally a newline from Cell #6
