Question 1:
Consider the context free grammar (CFG):
S → AB
(S being the start symbol)
A → aAb | aabb
B - cBd | cd
The grammar is strong LL(k).
a) Determine the value of k.
b) As a result of a) above, compute the corresponding look ahead sets (for each
production).
c) As a result of b) above, write (in C++ pseudo code) the corresponding recursive descent
parser (for the grammar).
NB: Assume that
1. the procedure: void expect(char token), has been coded appropriately
2. The next k symbols will be contained in the character array: symbol
3. the procedure: bool equal(char* str1, char * str2), has been coded appropriately to
compare the two C(++) strings, strl and str2.
