2. Using the syntax of C, write a recursive-descent subprogram that corresponds to the following EENF rule: In this rule, (and) are not metasymbols. You may assume that the lex function reads a single lexeme, whose token code is left in the nextToken variable. Assume that the codes for the while, left parenthesis, right parenthesis, and semicolon tokens are WHILE CODE, LEFTPAREN CODE, RIGHTPAREN CODE, and SEMICOLON CODE, respectively. Have your function call the error function if it detects an error. 2.
