Question

Write a BNF grammar for the for loop statement of C. Assume this is the 89 standard that does NOT allow new variables as C++ did (not allowed is the int in for (int i=0; i<5; i++). Also assume block is NOT a statement (different books take different take on this). Further assume <expression> and <statement> and <block> nonterminals are already defined (you dont' define them, just use them). Do not use the extended BNF notation.

Explanation / Answer

The BNFgrammar is :

<for> ::= for(<expression> ; <expression>; <expression)<block>

<block>: :=<statement_list>|<statement >

<statement_list>:: = <statement><statement_list> <statement>
