 My language no longer different from the C language.But I don't need data type like int or bool.You have to end every code statement with ";" and for the loop loop body should 
 be in between "{" and "}".Yo can write comment in two ways first one "//" starting with this all line runnin as a comment and the other one is "/*....*/" in this sign every
 character will be run as a comment.
