1.Structure of BF

The BF language is actually made of an array of size 30,000.Each cell occupies one byte,so its range is actually from 0-255.

[0][4][67][1][55][255][23][0]
^
So the ^ symbol actually indicates the present location in the program.

2.The Operators

The basic idea behind brainfuck is memory manipulation.Brain fuck has only 8 operators that are all written in single characters.Even though BF is restricted to these 8 characters and strictly restrictive any program that can be written in c can be written in brain fuck.

The eight operators are

* + increase byte under pointer
* - decrease byte under pointer
* > increase pointer
* < decrease pointer
* [ start a loop if byte under pointer is not 0
* ] return to matching [
* . print byte under pointer to standard output (often screen)
* , read input from standard input (often keyboard) to byte under pointer

3.The Arithematic calculations

1.Addition
2.Subtraction
3.Multiplication
4.Division
