determine the terminal symbols and non-terminal symbols and the start symbols from the following grammar:
<program> ==> <stmts>
<stmts> ==> <stmt> | <stmt> ; <stmts>
<var> ==> a | b | c | d
<expr> ==> <term>+<term>|<term>-<trerm>
<term> == > <var>|const
Terminal symbol :- | , ; , + , -
Non terminal symbol :- program , stmts, stmt, var ,expr , term
Start symbol :- var

Consider the following grammar (G1) for simple assignment statements. (The symbols in double quotation marks are terminal symbols.) assign → id “ = ” expr id → “A” | “B” | “C” expr → expr “ + ” expr | expr “ ∗ ” expr | “(” expr “)” | id a) Give a (leftmost) derivation for string A = B ∗ A + C. b) Give the parse tree for string A = B ∗ A + C. c)...

16. A grammar can be expressed in BNF notation. There are two types of symbols in BNF expressions. Non-terminal symbols are typically A. Abstract concepts that need to be further defined B. The symbols that would appear in a grammar file C. The symbols that would appear in a source code file D. Metasymbols that are used by BNF grammar types to help describe rules 17.
