Right Answer is: A
SOLUTION
Statement A: False
Symbol table can be used during all phases of the compiler
Statement B: True
A pretty printer does analyse a program and print it in such a way that the structure of the program becomes early visible
Statement C: True
YACC is a tool to build the LALR parsing table
Statement D: True
If a grammar is LALR(1), then it is not necessary for it to be SLR(1).
